So. Today I noticed that if you are about to make a sale item into TP from your backpack but forget it for some reason and deposit all collectibles to your bank. The item stays in your TP sales list if you try to sell if before you make the deposit while it is not in your inventory anymore.
After that deposit if you try to press sell to item in question while it is already in bank and not in your inventory it causes game to crash to desktop.
I hope I made sense. :S
Steps to reproduce: Rightclick collectible item and select sell at trading post. -> Select deposit all collectibles from your inventory. -> Press sell in Trading Post window. -> Game Crashes.
