If you kill a boss mob and they drop xp loot in a stack of 10, when you grant someone the ability to take 1 item out, it only allows them to take 1 of the stack not the full 10, then the other 9 disappear.
So if 10 Granite Stones drop and they want the full stack, it allows them to get 1, the other 9 go poof. The entire stack of 10 should be counted as the 1 item.
