I think I've noticed my first bug -- when playtesting, I can get duplicates of items by selecting a blank square in the inventory screen and pressing "equip selected." For each square I perform this action on, I get an item duplicate of what's in my main hand when I return to the inventory screen, as in the image below. I've tried this in mods and can replicate it there.
