Hey, so i've put the ReplaceVanillaWither to false, and spawned a wither but i've dropped to 0 fps, the wither was named "Wither" and is entity with waila was Wither, but idk it has the head of steve and the skin of steve and boom, 0 fps like there was 600 withers in the same wither

Any console errors? I've never heard or seen this to happen so not much I can really do without some sort of log. this mod is also really not being supported right now either.

Hey, sorry for the late response, I didn't checked the console while getting the mod set to false, i'll try to reproduce it in a self hosted server however
