See This issue for all the details of what happened. The only other notes I have are that I had the enchantments added by the mod disabled, which may be the trigger for the bug, and that it also affected the Enchanting Infuser from the mod of the same name, so the bug might actually affect vanilla enchanting as well as Apotheosis

Sorry for the long wait, been having personal issues alongside slight burnout for coding mods so I cant guarantee my next response will be quick either

I didnt see any major issues, but I would need to do a personal look. I do know that my way of doing it doesnt unregister the items so I wouldnt be surprised if thats the case. Does it cause this crash with them enabled?
