So i am in a server with the
Create Mod forge 1.20.1
Create: Big cannons forge 1.20.1
Create: steam ‘n’ rails forge 1.20.1
Wich has been working fine for me on curse forge me and a freind then went and built a train and when he clicked assemble train my game crashed with the “org.spongepowered.asm.mixin.transformer.throwable.mixintransformererror” message showing i was wonering if there is a fix the game is fine other than when a train starts
The error you have sent is a generic mixins error whereby the mod that uses mixins is responsible for its own issues.
Sadly because your issue isnt sponge vanilla or sponge forge related, its likely even if you send the whole error we would be able to help solve the issue.
My suggestion is to contact the owner of the mod via either discord, github, curseforge, etc
I fixed the issue but thanks
