You are not the first to report this issue with multicraft and BetterMC

All I can tell you is that one of the mods is hard crashing the game with a broken mixin.

There is no other information in the error information, it doesn't say which mod.

20.03 12:28:33 [Server] INFO Caused by: org.spongepowered.asm.mixin.transformer.throwables.MixinTransformerError: An unexpected critical error was encountered

You need to speak to the BetterMC modpack developers or multicraft.

If you find out what the real problem is, please report it back here for others.

Hi, any update on this? I'm having a similar issue.
