i get an error loading create 0.5.1h im in 1.20.1 and i dont know what to do
it says Create (create) has failed to load correctly org.spongepowered.asm.mixin.transformer.throwables.MixinTransformerError: An unexpected critical error was encountered
Not a sponge error as 1.20.1 didnt have a sponge forge release. This is a mixin error whereby the mod author is responsible.
Would also need the whole error not just the title to assist further.
Whole error can be found in the logs file in your logs folder (on server) or .minecraft/logs (on client)
Holla, i know it’s been a while and i’m not the original poster but if you don’t mind i’m having the same issue rn…

Reply is the same. Not a sponge issue, so report it to the mod creator. The mod is
