    Whenever I try to install Optiforge, I get this

    “The game crashed whilst initializing game
    Error: org.spongepowered.asm.mixin.transformer.throwables.MixinTransformerError: An unexpected critical error was encountered
    Exit Code: -1”

    Previous versions never did this…no idea what the problem is.
