The main reason I wanted to use NEI was because NEI had a nifty Enchantment list of all possible enchantments in the modpack. In 1.12.2, im forced to use JEI since they are kind of the only provider and people asking for Enchantment info in JEI always get told "Use NEI they have that". I was happy to discover that a 1.12 version exists, only to find out that sadly, pressing the enchantment hotkey or the potions hotkey does nothing.

I don't even know what info I can provide to help track the issue, so tell me if you need anything.

Edit: Unfortunately, dumping enchantment data to a csv results in an empty 0kb file, too

You need to be in Cheat mode to use the enchantment menu / potion creator. I can confirm it does work in 1.12.
