Hello. So, I tried to turn on atm6 modpack and minecraft said that I don't have the geckolib 36.1.1 version... But I looked online for it and there's no such thing as of yet... I don't think I'm playing minecraft, the minecraft's playing me....

Please post a screenshot of the actual error message.

It means you don't have Forge version 36.1.1, you need to update the forge version of ATM6
