Identify the Problem
If your game crashes during startup with errors mentioning Mixin versions or missing classes like net.minecraft.client.main.Main, you likely have mods using incompatible Mixin versions. This mod resolves those conflicts by prioritizing Mixin 0.8.
Check Your Crash Log
1. Launch the game and let it crash
2. Open your crash log (usually in .minecraft/crash-reports/)
3. Search for keywords: "Mixin", "version", or "class not found"
4. If you see references to Mixin 0.7 alongside newer mods, the compatibility mod will help
Verify the Fix
Once installed, relaunch the game. If the crash was Mixin-related, the game should now progress past the launcher screen. The mod works silently—you won't see it in your mod list or in-game. If crashes persist, the issue may be unrelated to Mixin versions.
