Hotbar keys casting the wrong spell

[Glenn the Great]

I currently have F5 mapped to Fire, but when I click it, it casts Goblin Punch.

I think I may have originally placed Goblin Punch on F5 before moving it to F2, so maybe the game didn't properly update some internal hotkey mapping when I swapped them around.

I believe this may also be due to swapping the location of spells in your spell listing. It's interesting though, I'll look into this.
