I decided to add some more mods to my existing ones and chose some from atm7. quark was one of the many mods that may be an issue. since then whenever I load a world, it gives me the error "errors in currently selected datapacks" and gives me two options safemode and return to main menu. it then crashes when I click safemode. any idea on how to fix this? haven't tried removing all the mods but if it comes to that I will. thanks in advance.
