I have bought game for 9 tf keys. Game went to my internal dispenser.tf inventory. Then I go to inventory and want withdraw game to my Steam account, so I'm selecting the game, clicking withdraw and getting "Please select items before using this function.". I am able to put it on market, but I am unable to withdraw to my Steam? What a... now I have no keys and no game. Tried several times and nothing...

EDIT: Around 10 minutes after this post, I've got offer on my Steam with the game. I didn't try withdraw again after this post, so someone from admins read it and push it, or system simply needs around 20 minutes...

You are supposed to wait for the system to send you the game before you try to withdraw from shop inventory. Normally the item won't end up in your inventory unless the system fails to send you a trade offer. In which case an admin will put the item in your shop inventory.
