I picked up the new Five Finger Discount ability on dungeon level 6 or so, and while it works as intended when I have a space open in my bag, if my bags are full (which they often are if I have not found a shop recently) I get the message that I have stolen an item, then the item never appears. In all other cases where you get things that can't fit in your bag (crafting, quest rewards, etc) the item just gets dumped on the ground at your feet so you can get it after you make room, but not in this instance.
