Items disapearing

So if you have enough items, and sell a champion with an item on it, it will just straight up vanish from the game, the item that is. So if you have a shitload of components that you havent had the need to actually combine yet, looking for perfect items, ect you will lose the item. The same thing happens if you open an orb, you might have thought it was empty or something, but nope, enough items on your board and they just vanish, banished to the same relm your LP just went.
