If you run an instance with lithium and BadOptimizations, the game will crash because lithium and BadOptimizations both try to optimize the same thing. Since Lithium is such a big mod and many people who would be looking for more performance already have it, could you remove this optimization from BadOptimizations?

in progress

Fixed, MixinDataTracker will no longer apply if Lithium is present.
For now you'll have to build off source for the fix, I'm not posting it to Modrinth until 1.20.1 + 1.20.3 support.
