+### "Server" Term and Definiton
+
+"HytaleServer.jar", which called as "Server", functions as the place of authentication of the client that supposed to go to Hytale Official Authentication System but we managed our way to redirect it on our service (Thanks to Sanasol), handling approximately thousands of players worldwide to play this game for free.
+
+Kindly support us via [our Buy Me a Coffee link](https://buymeacoffee.com/hf2p) if you think our launcher took a big part of developing this Hytale community for the love of the game itself. 
+**We will always advertise, always pushing, and always asking, to every users of this launcher to purchase the original game to help the official development of Hytale**. 
+
+### Server Directory Location
+
+Here are the directory locations of Server folder if you have installed 
+- **Windows:** `%localappdata%\HytaleF2P\release\package\game\latest\Server`
+- **macOS:** `~/Library/Application Support/HytaleF2P/release/package/game/latest/Server`
+- **Linux:** `~/.hytalef2p/release/package/game/latest/Server`
+
+> [!NOTE]
+> This location only exists if the user installed the game using our launcher. The `Server` folder needed to auth the HytaleClient to play Hytale online
+> (for now; we planned to add offline mode in later version of our launcher).
+
+> [!IMPORTANT]
+> Hosting a dedicated Hytale server will not need the exact similar tree. You can put it anywhere, as long as the directory has `Assets.zip` which
+> can be acquired from our launcher via our `HytaleServer.rar` server file (which contains patched `HytaleServer.jar`, `Assets.zip`, and `run_server` scripts in `.sh & .bat`.

+
+# B. Local Dedicated Server
+
+This option is perfect for any players size. From small to high.
+
+## 1. Using Playit.gg (Recommended) ✅
 
 Free tunneling service - only the host needs to install it:
 
-1. **Download [playit.gg](https://playit.gg/)** and run it - Connect your account from the terminal (do not close it when playing on the server)  
-2. **Add a tunnel** - Select "UDP", tunnel description of "Hytale Server", port count `1`, and local port `5520`
-3. **Start the tunnel** - You'll get a public address like `xx-xx.gl.at.ply.gg:5520`
-4. **Share the address** - Friends connect directly using this address
+1. Go to https://playit.gg/login and **Log In** with your existing account, **Create Account** if you don't have one
+2. Press "Add a tunnel" > Select `UDP` > Tunnel description of `Hytale Server` > Port count `1` > and Local Port `5520`
+3. Press **Start the tunnel** (or you can just run the Playit.gg.EXE if you already installed it on your machine) - You'll get a public address like `xx-xx.gl.at.ply.gg:5520`
+4. Go to https://playit.gg/download : `Installer` (Windows) or `x86-64` (Linux) or follow `Debian Install Script` (Debian-based only) 
+   * Windows: Install the `playit-windows.msi`
+   * Linux:
+     * Right-click file > Properties > Turn on 'Executable as a Program' | or `chmod +x playit-linux-amd64` on terminal
+     * Run by double-clicking the file or `./playit-linux-amd64` via terminal
+5. Open the URL/link by `Ctrl+Click` it. If unable, select the URL, then Right-Click to Copy (`Ctrl+Shift+C` for Linux) then Paste the URL into your browser to link it with your created account.
+6. **WARNING: Do not close the terminal if you are still playing or hosting the server**
+7. Once it done, download the `run_server_with_tokens` script file (`.BAT` for Windows, `.SH` for Linux) from our Discord server > channel `#open-public-server`
+8. Put the script file to the `Server` folder in `HytaleF2P` directory (`%localappdata%\HytaleF2P\release\package\game\latest\Server`)
+9. Copy the `Assets.zip` from the `%localappdata%\HytaleF2P\release\package\game\latest\` folder to the `Server\` folder. (TIP: You can use Symlink of that file to reduce disk usage!)
+10. Double-click the .BAT file to host your server, wait until it shows:
+```
+===================================================
+Hytale Server Booted! [Multiplayer, Fresh Universe]
+===================================================
+```
+11. Connect to the server by go to `Servers` in your game client, press `Add Server`, type `localhost` in the address box, use any name for your server.
+12. Send the public address in Step 3 to your friends.
 
-Works with both Online Play and dedicated servers. No software needed for players joining.
-
-#### Option 2: Radmin VPN
+## 2. Using Radmin VPN
 
 Creates a virtual LAN - all players need to install it:
 
-1. **Download [Radmin VPN](https://www.radmin-vpn.com/)** - All players install it
-2. **Create a network** - One person creates, others join with network name/password
-3. **Host via Online Play** - Use your Radmin VPN IP instead
-4. **Friends connect** - They'll see you on the virtual LAN
+1. Download [Radmin VPN](https://www.radmin-vpn.com/) - All players install it
+2. One person create a room/network, others join with network name/password
+3. Host joined the world, others will connect to it.
+4. Open Hytale Game > Servers > Add Servers > Direct Connect > Type IP Address of the Host from Radmin.
 
-Both options bypass all NAT/CGNAT issues. But for **Windows machines only!**
+These options bypass all NAT/CGNAT issues. But for **Windows machines only!**
 
-#### Option 3: Tailscale

-## Part 2: Dedicated Server (Advanced)
+# C. 24/7 Dedicated Server (Advanced)
 
 For 24/7 servers, custom configurations, or hosting on a VPS/dedicated machine.
 
-### Quick Start
+## Step 1: Get the Files Ready
 
-#### Step 1: Get the Server JAR
+### Prequisites
 
-The server scripts will automatically download the pre-patched server JAR if it's not present.
+1. `HytaleServer.jar` (pre-patched for F2P players; dual-auth soon for Official + F2P play)
+2. `Assets.zip`
+3. `run_scripts_with_token.bat` for Windows or `run_scripts_with_token.sh` for macOS/Linux
 
-**Option A:** Let the scripts download automatically (requires `HYTALE_SERVER_URL` to be configured)
+> [!NOTE]
+> The `HytaleServer.rar` available on our Discord Server (`#open-public-server` channel; typo on the Discord, not `zip`) includes all of the prequisites.
+> Unfortunately, the JAR inside the RAR isn't updated so you'll need to download the JAR from the link on Discord.
 
-**Option B:** Manually place `HytaleServer.jar` (pre-patched for F2P) in the Server directory:
+> [!TIP]
+> You can copy `Assets.zip` generated from the launcher to be used for the dedicated server. It's located in `HytaleF2P/release/package/game/latest`. 
 
-- **Windows:** `%localappdata%\HytaleF2P\release\package\game\latest\Server`
-- **macOS:** `~/Library/Application Support/HytaleF2P/release/package/game/latest/Server`
-- **Linux:** `~/.hytalef2p/release/package/game/latest/Server`
 
-If you have a custom install path, the Server folder is inside your custom location under `HytaleF2P/release/package/game/latest/Server`.
+## Step 2: Place `HytaleServer.jar` in the `Server` directory
 
-#### Step 2: Run the Server
+* Windows
+  * `%localappdata%\HytaleF2P\release\package\game\latest\Server`
+* macOS
+  * `~/Library/Application Support/HytaleF2P/release/package/game/latest/Server`
+* Linux
+  * `~/.hytalef2p/release/package/game/latest/Server`
+* If you have a custom install path, the Server folder is inside your custom location under
+  * `HytaleF2P/release/package/game/latest/Server`.
+
+## Step 3: Run the Server
 
 **Windows:**
 ```batch
-cd scripts
 run_server.bat
 ```
 
 **macOS / Linux:**
 ```bash
-cd scripts
 ./run_server.sh
 ```
 
-The scripts will:
-1. Find your game installation automatically
-2. Download the pre-patched server JAR if needed
-3. Fetch session tokens from the auth server
-4. Start the server
-
-#### Step 3: Connect Players
-
-Share your server IP address with players. They connect via the F2P Launcher's server browser or direct connect.

+
+## Windows Issues
+
+### "Failed to connect to server" / Server won't boot
+
+**Symptoms:** Singleplayer world fails to load, "Server failed to boot" error.
+
+**Solution - Whitelist in Windows Firewall:**
+1. Open **Windows Settings** > **Privacy & Security** > **Windows Security**
+2. Click **Firewall & network protection** > **Allow an app through firewall**
+3. Click **Change settings**
+4. Find `HytaleClient.exe` and check both **Private** and **Public**
+5. If not listed, click **Allow another app** and browse to:
+   ```
+   %localappdata%\HytaleF2P\release\package\game\latest\Client\HytaleClient.exe
+   ```
+
+### Duplicate mod error
+
+**Symptoms:** `java.lang.IllegalArgumentException: Tried to load duplicate plugin`
+
+**Solution:**
+1. Navigate to your mods folder:
+   ```
+   %localappdata%\HytaleF2P\release\package\game\latest\Client\UserData\Mods
+   ```
+2. Remove any duplicate `.jar` files
+3. Restart the launcher
+
+### SmartScreen blocks the launcher
+
+**Solution:**
+1. Click **More info**
+2. Click **Run anyway**
+
+---
+
+## Linux Issues
+
+### GPU not detected / Using software rendering (llvmpipe)
+
+**Symptoms:**
+- Game uses integrated GPU instead of dedicated GPU
+- Very low FPS / unplayable performance
+- Play button not clickable
+- Log shows `llvmpipe` instead of your GPU
+
+**Solution for NVIDIA:**
+```bash
+__EGL_VENDOR_LIBRARY_FILENAMES=/usr/share/glvnd/egl_vendor.d/10_nvidia.json ./HytaleF2P.AppImage
+```
+
+**Solution for AMD (hybrid GPU systems):**
+```bash
+DRI_PRIME=1 ./HytaleF2P.AppImage
+```
+
+**Permanent fix - Create a launcher script:**
+```bash
+#!/bin/bash
+export __EGL_VENDOR_LIBRARY_FILENAMES=/usr/share/glvnd/egl_vendor.d/10_nvidia.json
+export DRI_PRIME=1
+./HytaleF2P.AppImage
+```
+
+**Note:** On some desktop systems with AMD iGPU + dGPU, the GPU selector may be inverted (selecting iGPU actually uses dGPU). Use whichever option works.
+
+### SDL3_image / libpng errors
+
+**Symptoms:**
+- `DllNotFoundException: Unable to load shared library 'SDL3_image'`
+- `libpng` related errors
+- Game crashes on startup
+
+**Solution - Install dependencies:**
+
+**Fedora / RHEL:**
+```bash
+sudo dnf install libpng libpng-devel
+```
+
+**Debian / Ubuntu:**
+```bash
+sudo apt install libpng16-16 libpng-dev libgdiplus libc6-dev
+```
+
+**Arch Linux:**
+```bash
+sudo pacman -S libpng
+```
+
+**Alternative - Replace corrupted library:**
+```bash
+cd ~/.hytalef2p/release/package/game/latest/Client/
+mv libSDL3_image.so libSDL3_image.so.bak
+wget https://github.com/user-attachments/files/24710966/libSDL3_image.zip
+unzip libSDL3_image.zip
+chmod 644 libSDL3_image.so
+rm libSDL3_image.zip
+```
+
+### AppImage won't launch / FUSE error
+
+**Solution:**
+```bash
+# Debian/Ubuntu
+sudo apt install libfuse2
+
+# Fedora
+sudo dnf install fuse
+
+# Arch
+sudo pacman -S fuse2
+```
+
+### Missing libxcrypt.so.1
+
+**Solution:**
+```bash
+# Fedora/RHEL
+sudo dnf install libxcrypt-compat
+
+# Arch
+sudo pacman -S libxcrypt-compat
+```
+
+### Wayland display issues
+
+**Symptoms:** Game doesn't launch, stuck at loading, or display glitches on Wayland.
+
+**Solution - Force X11:**
+```bash
+GDK_BACKEND=x11 ./HytaleF2P.AppImage
+```
+
+**Alternative - Electron Wayland hint:**
+```bash
+ELECTRON_OZONE_PLATFORM_HINT=auto ./HytaleF2P.AppImage
+```
+
+### Steam Deck / Gamescope issues
+
+**Solution 1 - Add custom launch options in Steam:**
+```
+ELECTRON_OZONE_PLATFORM_HINT=x11 %command%
+```
+
+**Solution 2 - Launch from Desktop Mode** instead of Game Mode.
+
+**Solution 3 - Force X11:**
+```bash
+GDK_BACKEND=x11 ./HytaleF2P.AppImage
+```
+
+### Ubuntu LTS-based distros (Linux Mint, Zorin OS, Pop!_OS)
+
+These distributions may have compatibility issues due to older system packages. This is a limitation of the Hytale game client, not the launcher.
+
+**Workarounds:**
+1. Install all dependencies listed above
+2. Try the SDL3_image replacement
+3. Consider using a more recent distribution or Flatpak/AppImage with bundled dependencies
+
+---
+
+## macOS Issues
+
+### "Butler system error -86" (Apple Silicon)
+
+**Symptoms:** `Butler execution failed: spawn Unknown system error -86` (EXC_BAD_CPU_TYPE)
+
+**Cause:** Butler (the update tool) is x86_64 only.
+
+**Solution - Install Rosetta 2:**
+```bash
+softwareupdate --install-rosetta
+```
+
+Then restart the launcher.
+
+### Auto-update fails with code signature error
+
+**Symptoms:**
+```
+Code signature at URL did not pass validation
+domain: 'SQRLCodeSignatureErrorDomain'
+```
+
+**Solution - Manual update:**
+1. Download the latest version manually from [Releases](https://github.com/amiayweb/Hytale-F2P/releases/latest)
+2. Backup your data first (see [Backup Locations](#backup-locations))
+3. Install the fresh download
+
+### "Unidentified developer" warning
+
+**Solution:**
+1. Open **System Settings** > **Privacy & Security**
+2. Scroll to **Security** section
+3. Find the message about "Hytale F2P Launcher"
+4. Click **Open Anyway**
+5. Authenticate and click **Open**
+
+### App won't open (quarantine)
+
+**Solution:**
+```bash
+xattr -rd com.apple.quarantine /Applications/Hytale-F2P-Launcher.app
+```
+
+---
+
+## Connection & Server Issues
+
+### "Failed to connect to server" in Singleplayer
+
+**Possible causes:**
+1. Windows Firewall blocking (see [Windows section](#failed-to-connect-to-server--server-wont-boot))
+2. Patched server JAR download failed
+3. Regional network restrictions
+
+**Solution - Check patched JAR:**
+1. Look for `HytaleServer.jar` in:
+   - Windows: `%localappdata%\HytaleF2P\release\package\game\latest\Server\`
+   - Linux: `~/.hytalef2p/release/package/game/latest/Server/`
+   - macOS: `~/Library/Application Support/HytaleF2P/release/package/game/latest/Server/`
+2. If missing or very small, the download may have failed
+
+**Solution - Regional restrictions:**
+
+Some countries (Russia, Turkey, Indonesia, etc.) may have issues accessing download servers.
+- Try using a VPN for the initial download
+- Once downloaded, the patched JAR is cached locally
+
+### "Infinite Booting Server" / Server stuck loading
+
+**Solution:**
+1. Check if the patched JAR downloaded successfully (see above)
+2. Ensure your GPU meets minimum requirements
+3. Check launcher logs for specific errors
+4. Try with a VPN if in a restricted region
+
+### "Connection timed out from inactivity"
+
+**This is expected behavior.** Sessions have a 10-hour TTL and will timeout after extended inactivity. Simply reconnect to continue playing.
+
+---
+
+## Authentication & Token Issues
+
+### "Invalid identity token" / "Failed to start Hytale"
+
+**Solution:**
+1. **Restart the launcher** - This fetches fresh tokens
+2. **Check system time** - JWT validation requires accurate system time
+3. **Clear cached tokens:**
+   - Delete `config.json` from your HytaleF2P folder
+   - Restart the launcher
+   - Re-enter your username
+
+**Locations:**
+- Windows: `%localappdata%\HytaleF2P\config.json`
+- Linux: `~/.hytalef2p/config.json`
+- macOS: `~/Library/Application Support/HytaleF2P/config.json`
+
+### Token refresh errors
+
+If you see issuer mismatch errors in logs:
+1. Delete `config.json` and `player_id.json`
+2. Restart the launcher
+3. This forces a fresh authentication
+
+---
+
+## Avatar & Cosmetics Issues
+
+### Avatar/skin changes not saving
+
+**This is a known F2P limitation:**
+- F2P mode has no password protection for usernames
+- Anyone can use any username
+- Cosmetics are stored server-side by username
+- If someone else uses your username, they can change your cosmetics
+
+**Workaround:** Use a unique username that others are unlikely to choose.
+
+### Character invisible / Customization crashes
+
+**Solution:**
+1. Use **Repair Game** in launcher Settings
+2. Verify `Assets.zip` exists in your game folder
+3. Clear cached assets:
+   - Windows: Delete `%localappdata%\HytaleF2P\release\package\game\latest\Client\UserData\CachedAssets\`
+4. Restart the launcher
+
+### Avatar creator shows "Offline Mode"
+
+**Cause:** Cannot connect to auth server.
+
+**Solution:**
+1. Check your internet connection
+2. Test connectivity: Open `https://auth.sanasol.ws/health` in browser (should show "OK")
+3. Check if firewall is blocking the connection
+4. Try disabling VPN (or enabling one if in restricted region)
+
+---
+
+## General Issues
+
+### Mods not showing up
+
+**Solution:**
+1. Ensure mods are placed in the correct folder:
+   - Windows: `%localappdata%\HytaleF2P\release\package\game\latest\Client\UserData\Mods\`
+   - Linux: `~/.hytalef2p/release/package/game/latest/Client/UserData/Mods/`
+   - macOS: `~/Library/Application Support/HytaleF2P/release/package/game/latest/Client/UserData/Mods/`
+2. Verify mod files are `.jar` format
+3. Check launcher logs for mod loading errors
+
+### Game updates delete configurations/mods
+
+**This is a known issue being worked on.**
+
+**Prevention - Always backup before updating:**
+- Server configs and worlds
+- Mods folder
+- `config.json` and `player_id.json`
+
+See [Backup Locations](#backup-locations) below.
+
+### Play button not clickable
+
+Usually caused by GPU detection failure. See [GPU not detected](#gpu-not-detected--using-software-rendering-llvmpipe).
+
+**Alternative:**
+1. Go to **Settings** > **Graphics**
+2. Manually select your GPU
+3. Restart the launcher
+
+### Read timeout errors
+
+**Cause:** Network connectivity issues.
+
+**Solutions:**
+1. Check your internet connection stability
+2. Try using a VPN
+3. Check firewall settings
+4. Try at a different time (server load varies)
+
+---
+
+## Known Limitations
+
+### Linux ARM64 not supported
+
+Hytale does not provide ARM64 game client builds. The launcher downloads from official Hytale servers which only provide:
+- Windows x64
+- macOS (Universal/Intel)
+- Linux x64
+
+This is outside our control.
+
+### F2P Username System
+
+- No password protection for usernames
+- Anyone can claim any username
+- Cosmetics shared by username
+- UUIDs generated based on username
+
+A per-player password system is planned for future versions.
+
+### Session Timeout
+
+Game sessions have a 10-hour TTL. This is by design for security.

+# UUID/Skin Reset Bug Fix Plan
+
+## Problem Summary
+
+Players experience random skin/cosmetic resets without intentionally changing anything. The root cause is that the UUID system has multiple failure points that can silently generate new UUIDs or use the wrong UUID during gameplay.
+
+**Impact**: Players lose their customized cosmetics/skins randomly, causing frustration and confusion.
+
+**Status**: ✅ **FIXED** - All critical and high priority bugs have been addressed.
+
+---
+
+## Implementation Summary
+
+### What Was Fixed
+
+| Bug | Severity | Status | Description |
+|-----|----------|--------|-------------|
+| BUG-001 | Critical | ✅ Fixed | Username not loaded before play click |
+| BUG-002 | High | ✅ Fixed | isFirstLaunch() always returns true |
+| BUG-003 | Critical | ✅ Fixed | Silent config corruption returns empty object |
+| BUG-004 | Critical | ✅ Fixed | Non-atomic config writes |
+| BUG-005 | High | ✅ Fixed | Username fallback to 'Player' |
+| BUG-006 | Medium | ✅ Fixed | Launch overwrites username every time |
+| BUG-007 | Medium | ✅ Fixed | Dual UUID systems (playerManager vs config) |
+| BUG-008 | High | ✅ Fixed | Error returns random UUID |
+| BUG-009 | Medium | ✅ Fixed | Username case sensitivity |
+| BUG-010 | Medium | ⏳ Pending | Migration marks complete on partial failure |
+| BUG-011 | Medium | ⏳ Pending | Race condition on concurrent config access |
+| BUG-012 | High | ✅ Fixed | UUID modal isCurrent flag broken |
+| BUG-013 | High | ✅ Fixed | UUID setting uses unsaved DOM username |
+| BUG-014 | Medium | ✅ Fixed | No way to switch between saved identities |
+| BUG-015 | High | ✅ Fixed | installGame saves username (overwrites good value) |
+| BUG-016 | High | ✅ Fixed | Username rename creates new UUID instead of preserving |
+| BUG-017 | Medium | ✅ Fixed | UUID list not refreshing when player name changes |
+| BUG-018 | Low | ✅ Fixed | Custom UUID input doesn't allow copy/paste |
+
+---
+
+## User Scenario Analysis
+
+All user scenarios have been analyzed for UUID/username persistence:
+
+| Scenario | Risk | Status | Details |
+|----------|------|--------|---------|

+## Detailed Bug List & Fixes
+
+---
+
+### BUG-001: Username Not Loaded Before Play Click (CRITICAL) ✅ FIXED
+
+**Category**: A - Race Condition
+
+**Location**:
+- `GUI/js/launcher.js`
+- `GUI/js/settings.js`
+
+**Problem**: If user clicks Play before settings DOM initializes, returns 'Player' silently.
+
+**Fix Applied**:
+- launcher.js now uses `checkLaunchReady()` API to validate before launch
+- Loads username from backend config (single source of truth)
+- Blocks launch and shows error if no username configured
+- Navigates user to settings page to set username
+
+---
+
+### BUG-002: `isFirstLaunch()` Always Returns True (HIGH) ✅ FIXED
+
+**Category**: B - Silent Failure
+
+**Location**: `backend/core/config.js`
+
+**Problem**: Function always returns `true` even when user has data (typo: `return true` instead of `return false`).
+
+**Fix Applied**:
+- Fixed return statement: `return true` → `return false`
+
+---
+
+### BUG-003: Silent Config Corruption Returns Empty Object (CRITICAL) ✅ FIXED
+
+**Category**: B - Silent Failure
+
+**Location**: `backend/core/config.js`
+
+**Problem**: Corrupted config silently returns `{}`, causing UUID regeneration.
+
+**Fix Applied**:
+- Added config validation after load
+- Implemented backup config system (config.json.bak)
+- Tries loading backup if primary fails
+- Logs detailed errors for debugging
+
+---
+
+### BUG-004: Non-Atomic Config Writes (CRITICAL) ✅ FIXED
+
+**Category**: C - Data Integrity
+
+**Location**: `backend/core/config.js`
+
+**Problem**: Direct write can corrupt file if interrupted. Silent error logging.
+
+**Fix Applied**:
+- Atomic write: write to temp file → verify JSON → backup current → rename
+- Throws error on save failure (no silent continuation)
+- Cleans up temp file on failure
+
+---
+
+### BUG-005: Username Fallback to 'Player' (HIGH) ✅ FIXED
+
+**Category**: B - Silent Failure
+
+**Location**: `backend/core/config.js`
+
+**Problem**: Missing username silently falls back to 'Player', causing wrong UUID.
+
+**Fix Applied**:
+- `loadUsername()` returns `null` instead of 'Player'
+- Added `loadUsernameWithDefault()` for display purposes
+- Added `hasUsername()` helper function
+- All callers updated to handle null case explicitly
+
+---
+
+### BUG-006: Launch Overwrites Username Every Time (MEDIUM) ✅ FIXED
+
+**Category**: D - Design Issue
+
+**Location**: `backend/managers/gameLauncher.js`
+
+**Problem**: If playerName parameter is wrong, it overwrites the saved username.
+
+**Fix Applied**:
+- Removed `saveUsername()` call from launch process
+- Username only saved when user explicitly changes it in Settings
+- Launch loads username from config (single source of truth)
+
+---
+
+### BUG-007: Dual UUID Systems (playerManager vs config) (MEDIUM) ✅ FIXED
+
+**Category**: D - Design Issue
+
+**Location**:
+- `backend/services/playerManager.js` → `player_id.json`
+- `backend/core/config.js` → `config.json` → `userUuids`
+
+**Problem**: Two independent UUID systems can desync.
+
+**Fix Applied**:
+- `playerManager.js` marked as DEPRECATED
+- All code uses `config.js` `getUuidForUser()`
+- Migration function added for legacy `player_id.json`
+
+---
+
+### BUG-008: Error Returns Random UUID (HIGH) ✅ FIXED
+
+**Category**: B - Silent Failure
+
+**Location**: `backend/services/playerManager.js`
+
+**Problem**: Any error generates random UUID, losing player identity.
+
+**Fix Applied**:
+- Now throws error instead of returning random UUID
+- Retry logic added (3 attempts before failure)
+- Caller must handle the error appropriately
+
+---
+
+### BUG-009: Username Case Sensitivity (MEDIUM) ✅ FIXED
+
+**Category**: D - Design Issue
+
+**Location**: `backend/core/config.js`
+
+**Problem**: "PlayerOne" and "playerone" are different UUIDs.
+
+**Fix Applied**:
+- `getUuidForUser()` uses case-insensitive lookup
+- Username stored with ORIGINAL case (preserves "Sanasol", "SaAnAsOl", etc.)
+- Lookup normalized to lowercase for matching
+- Case changes update the stored key while preserving UUID
+
+---
+
+### BUG-010: Migration Marks Complete Even on Partial Failure (MEDIUM) ⏳ PENDING
+
+**Category**: C - Data Integrity
+
+**Location**: `backend/utils/userDataMigration.js`
+
+**Problem**: Partial copy is marked as complete, preventing retry.
+
+**Status**: Not yet implemented - low priority since migration runs once.
+
+---
+
+### BUG-011: Race Condition on Concurrent Config Access (MEDIUM) ⏳ PENDING
+
+**Category**: A - Race Condition
+
+**Location**: `backend/core/config.js`
+
+**Problem**: No file locking - concurrent processes can overwrite each other.
+
+**Status**: Not yet implemented - would require `proper-lockfile` package. Low risk since launcher is single-instance.
+
+---
+
+### BUG-012: UUID Modal isCurrent Flag Broken (HIGH) ✅ FIXED
+
+**Category**: D - Design Issue
+
+**Location**: `main.js` - `get-all-uuid-mappings` IPC handler
+
+**Problem**: Case-sensitive comparison between normalized key (lowercase) and current username.
+```javascript
+// BROKEN:
+isCurrent: username === loadUsername()  // "player1" === "Player1" → FALSE
+```
+
+**Fix Applied**:
+- IPC handler now uses `getAllUuidMappingsArray()` from config.js
+- This function correctly compares against normalized username
+
+---
+
+### BUG-013: UUID Setting Uses Unsaved DOM Username (HIGH) ✅ FIXED
+
+**Category**: B - Silent Failure
+
+**Location**: `GUI/js/settings.js` - `performSetCustomUuid()`
+
+**Problem**: Gets username from DOM input field instead of saved config.
+```javascript
+// BROKEN:
+const username = getCurrentPlayerName();  // From UI input, not saved!
+```
+
+**Risk Scenario**: User types new name but doesn't save → opens UUID modal → sets custom UUID → UUID gets set for unsaved name while config has old name.
+
+**Fix Applied**:
+- Now loads username from backend config via `window.electronAPI.loadUsername()`
+- Shows error if no username is saved
+
+---
+
+### BUG-014: No Way to Switch Between Saved Identities (MEDIUM) ✅ FIXED
+
+**Category**: D - Design Issue
+
+**Location**: `GUI/js/settings.js` - UUID modal
+
+**Problem**: UUID modal showed list of usernames/UUIDs but no way to switch to a different identity.
+
+**Fix Applied**:
+- Added `switchToUsername()` function
+- New switch button (user-check icon) on non-current entries
+- Confirmation dialog before switching
+- Updates username input and refreshes UUID display
+
+---
+
+### BUG-015: installGame Saves Username (HIGH) ✅ FIXED
+
+**Category**: D - Design Issue
+
+**Location**: `backend/managers/gameManager.js` - `installGame()`
+
+**Problem**: `saveUsername(playerName)` call could overwrite good username with 'Player' default.
+
+**Fix Applied**:
+- Removed `saveUsername()` call from `installGame()`
+- Username only saved when user explicitly changes it in Settings
+
+---
+
+### BUG-016: Username Rename Creates New UUID (HIGH) ✅ FIXED
+
+**Category**: D - Design Issue
+
+**Location**: `backend/core/config.js` - `saveUsername()`
+
+**Problem**: When user changes their player name, a new UUID was generated instead of preserving the existing one. User's identity (cosmetics/skins) was lost on every name change.
+
+**Symptom**: Change "Player1" to "NewPlayer" → gets completely new UUID → loses all cosmetics.
+
+**Fix Applied**:
+- `saveUsername()` now handles UUID mapping renames atomically
+- When renaming: old username's UUID is moved to new username
+- When switching to existing identity: uses that identity's existing UUID
+- Case changes only: updates key casing, preserves UUID
+- Both username and userUuids saved in single atomic operation
+
+**Behavior After Fix**:
+```javascript
+// Rename: "Player1" → "NewPlayer"
+// Before: Player1=uuid-123, NewPlayer=uuid-NEW (wrong!)
+// After:  NewPlayer=uuid-123 (same UUID, just renamed)
+
+// Switch to existing: "Player1" → "ExistingPlayer"
+// Uses ExistingPlayer's existing UUID (switching identity)
+
+// Case change: "Player1" → "PLAYER1"
+// UUID preserved, key updated to new case
+```
+
+---
+
+### BUG-017: UUID List Not Refreshing on Name Change (MEDIUM) ✅ FIXED
+
+**Category**: E - UI/UX Issue
+
+**Location**: `GUI/js/settings.js` - `savePlayerName()`
+
+**Problem**: After changing player name in settings, the UUID modal list didn't refresh. The "Current" badge showed on the old username instead of the new one.
+
+**Fix Applied**:
+- Added `await loadAllUuids()` call after `loadCurrentUuid()` in `savePlayerName()`
+- UUID modal now shows correct "Current" badge after name changes
+
+---
+
+### BUG-018: Custom UUID Input Doesn't Allow Copy/Paste (LOW) ✅ FIXED
+
+**Category**: E - UI/UX Issue
+
+**Location**: `GUI/style.css`, `main.js`
+
+**Problem**: Two issues prevented copy/paste:
+1. The body element has `select-none` class (Tailwind) which applies `user-select: none` globally
+2. Electron's `setIgnoreMenuShortcuts(true)` was blocking Ctrl+V/C/X/A shortcuts
+
+**Fix Applied**:
+- Added `user-select: text` with all vendor prefixes to `.uuid-input` class
+- Removed `setIgnoreMenuShortcuts(true)` from main.js
+- Added early return in `before-input-event` handler to allow Ctrl/Cmd + V/C/X/A shortcuts
+- DevTools shortcuts (Ctrl+Shift+I/J/C, F12) remain blocked
+
+---
+
+## Translation Keys Added
+
+The following translation keys were added to `GUI/locales/en.json`:
+
+```json
+{
+  "notifications": {
+    "noUsername": "No username configured. Please save your username first.",
+    "switchUsernameSuccess": "Switched to \"{username}\" successfully!",
+    "switchUsernameFailed": "Failed to switch username",
+    "playerNameTooLong": "Player name must be 16 characters or less"
+  },
+  "confirm": {
+    "switchUsernameTitle": "Switch Identity",
+    "switchUsernameMessage": "Switch to username \"{username}\"? This will change your current player identity.",
+    "switchUsernameButton": "Switch"
+  }
+}
+```
+
+---
+
+## Testing Checklist
+
+After implementing fixes, verify:
+
+- [x] Launch with freshly installed launcher - UUID persists
+- [x] Change username in settings - UUID preserved (renamed, not new)
+- [x] Config corruption - recovers from backup
+- [x] Click Play immediately after opening - correct UUID used
+- [x] Manual update from GitHub - UUID persists
+- [x] Username with different casing - same UUID used, case preserved
+- [x] UUID modal shows correct "Current" badge
+- [x] UUID modal refreshes after username change
+- [x] Switch identity from UUID modal works
+- [x] Profile switching doesn't affect username/UUID
+- [x] Custom UUID input allows copy/paste
+
+---
+
+## Architecture: How UUID/Username Persistence Works
+
+**Config Structure** (`config.json`):
+```json
+{
+  "username": "CurrentPlayer",
+  "userUuids": {
+    "Sanasol": "uuid-123-abc",
+    "SaAnAsOl": "uuid-456-def",
+    "Player1": "uuid-789-ghi"
+  },
+  "hasLaunchedBefore": true
+}
+```
+
+**Key Design Decisions**:
+- Username stored with ORIGINAL case (e.g., "Sanasol", "SaAnAsOl")
+- UUID lookup is case-insensitive (normalized to lowercase for matching)
+- Username rename preserves UUID (atomic rename operation)
+- Profile switching does NOT affect username/UUID (shared globally)
+- All config writes use atomic pattern: temp file → verify → backup → rename
+- Automatic backup recovery if config corruption detected
+
+**Data Flow**:
+1. User sets username in Settings → `saveUsername()` handles rename logic → saves to config.json
+2. If renaming: UUID moved from old name to new name (same UUID preserved)
+3. Launch game → `checkLaunchReady()` validates username exists
+4. Launch game → `getUuidForUser(username)` gets UUID (case-insensitive lookup)
+5. UUID modal → shows all username→UUID mappings from config
+6. Switch identity → saves new username → gets that username's UUID
+
+---
+
+## Success Criteria
+
+- ✅ Zero silent UUID regeneration
+- ✅ Config corruption recovery working
+- ✅ No UUID change without explicit user action
+- ✅ Username rename preserves UUID
+- ✅ Username case is preserved in display
+- ✅ UUID modal correctly identifies current user
+- ✅ UUID modal refreshes on changes
+- ✅ Users can switch between saved identities
+- ✅ Copy/paste works in UUID input
+
+---
+
+## Remaining Work
+
+1. **BUG-010**: Verify migration completeness before marking done (low priority)
+2. **BUG-011**: Add file locking with `proper-lockfile` (low priority - single instance)
+3. Add telemetry for config load failures and UUID regeneration events
+
+## Completed Additional Tasks
+
+- ✅ Added translation keys to all 10 locale files (de-DE, es-ES, fr-FR, id-ID, pl-PL, pt-BR, ru-RU, sv-SE, tr-TR, en)
