Throw down an item in your inventory in which you have more than one of and put an item in your
quick belt. Walk away from the item and then walk toward it again. The exact second your about to
pick it up, click on an item in your quick belt. The item will read whatever the item on the ground is.
Then you will have a duplicate item in your inventory. Do not through it on the ground with the other
one or the game will destroy one of them.
