Strange thing but when I launch it crashes and says its colytras fault :

There was a severe problem during mod loading that has caused the game to fail

net.minecraftforge.fml.common.LoaderException: java.lang.RuntimeException: Error syncing field 'permissionMode' of class 'c4.colytra.common.config.ConfigHandler'!

Seams to have something to do with the permission mode of the config.

Any help is appreciated :D

BTW this mode is AMAZING 3

Also here is the full crash file:

Oh ok, thank you also sorry i just put it twice so you would see it, Sorry. :P

I believe I answered you on CurseForge as well, but can you try deleting your Colytra config file and letting a new one generate?
