When using RPG Tweaks and Enchantment Descriptions with Connectivity or TimeoutFixes (I used the latter before switching to the former), enchantment descriptions are forced to show on items even if they haven't been deciphered with a Scroll of Identification yet.

I have figured out the issue. Modrinth's version of RPG Tweaks doesn't include the fix for Enchantment Descriptions loading, but Curseforge's does.

Actually, the issue is not specific to those two mods. I'm also encountering it when installing YUNG's Better Dungeons. I don't know what the connecting thread could be.
