Bug/Glitch Occurrence Context

Only happens when Optifine is in the mods folder along with Legacy 4J. Happens while forge is loading right before the Mojang Screen.

Crash Report

What happened wrong?

Game Crashed before loading Mojang Logo or Title screen. Error: org.spongepowered.asm.mixin.transformer.throwables.mixintransformererror: an unexpected critical error was encountered

Optifine is closed source and it's not meant to work with L4J

Okay, that makes sense. I found a better alternative to what I was trying to use Optifine for anyway.
