Running latest version of EPM on Forge 36.0.48

I was using latest version of Optifine G7 iirc

yeah i had a pretty similar issue, because i had Optifine G6, which wasnt compatable, if you're using g6 upgrade to g7 (this is the 1.16.4 version of the mod btw) if you're not using optifine then idk man sorry.

Is it crashes if you only use the Epic Fight without any other mods?

having the same issue when trying to join my server

I didnt have this issue with 3.0.2

Heres the serverside crash report https://gist.github.com/koderian/f70e6e919c424d265a64e0090e05f93a

This looks like a mod conflict. Idk what causes this, but I've never got this crash when I executed epicfight without any mods.
