I've tried retrieving 2 TF2 keys for a previous Portal sale I did (as well as adding another copy of the same game to my pool), and even though the trade didn't go through when I went back to check on the store inventory, one of the keys where gone.
What should I do? I am unable to paste a screenshot from my Steam history to prove this since the transaction did not went through. However, one of the keys simply disappeared from my Store inventory afterwards. Here is the only thing I could find out on my Store history, says transaction is on "Rollback"?

And here is a screenshot referring to the sale of the game from my Store Bot History:

And if you check my history yourself you will see there is no record of trading the keys referred to that sale back to me at any point afterwards.
Plus, a bit earlier my bot traded a copy of Final Fantasy VII for 3 Dota keys, and even though I know there is an API problem to retrieve the Dota items, the fact is that the keys aren't even showing up on my store inventory.
Screenshot of that from my Store History as well:

So just to clarify, currently I am missing 1 TF2 key + 3 Dota 2 keys from my Store inventory. Also I am afraid that trying to retrieve or give any item to my bot will cause the same bug again, so I am on hold until you give me a position on this. Please have a look at the issue asap, Joto. Thank you.
