blue water

So basically the issue is whenever i attack a mob in fight mode the game immediately crashes. I know for sure it is epic fight mod causing this because I've ran the game picking out ever mod i have installed 1 by one to check. The error message it gives me says this: The game crashed whilst ticking player Error: java.lang.NoSuchMethodError: net.minecraft.entity.Entity.getDimensionsForge(Lnet/minecraft/entity/Pose;)Lnet/minecraft/entity/EntitySize; For the record my game version is 1.16.5
