Bug description
A description of what you expected to happen and what actually happened.

Hello, this mod has seemed to work smoothly with many mods i use to add more mobs to the game, but there is one fallback i have come across with this mod. If using optifine in any way. it crashed minecraft before the game can even be booted up. Im not sure how you could resolve this. But if you can, that would be greatly appreciated and make this mod have a much farther outreach.

I am playing on minecraft 1.20.1, using curseforge 47.1.44
