While enchanting some leggings with two maxed out enchants and trying to get a third, I clicked the add button and got an error report through quark: https://paste.dimdev.org/ekawocimev.mccrash

Clicking the button again creates another error message but the game doesn't crash. So far I haven't done much else but I don't think it's caused much of an issue elsewhere.
