I was able to fix this by disabling the mod, entering Minecraft, leaving, then re-enabling it. It also stops the portal gun from the portal gun mod from working.
EDIT: Upon uninstalling and reinstalling the mod, my game is very laggy and has trouble render chunks.
Is this the mod that you were using? It's still in beta, so expect game-breaking issues to occur. Report the bug to the mod author so that he can (attempt to) fix the issue.
Yep, sure was. It was on twitch so i didn't see it was in beta. (Or I was dumb and got it anyway, i don't know). Also where do I report this to the author? Is there a website?
