The problem is that when a chest has more slots and we try to throw an item there, it drops a square lower than it is actually dropped. This causes a shift of 1 later 2,3,4 squares, which will take you to a place where you can no longer see the slots of the chest and you can't pull the item from the very bottom. This makes it impossible to dismantle the chest and make the game very uncomfortable. This problem does not occur on high resolution, but some players cannot afford a higher resolution.
