buy/sell items bug

I dont know if to call this a bug or if it takes alot of coding to fix this:


If you enter a shop and click on an item to buy, and you discard the item back to the shop, you will get the "Do you really want to sell your <item> to the store". This is pretty stupid that you sell an item that you dont have.

NOTE: Don't try to do this in order to dupe gold. (It won't work, I've tried that )

It can be confusing in some points in the game.
