Auction House never return my items.. I just notice i dont have my skorn...and probably took some of my other items!!
If you browse around the forums a bit, you will notice it is fairly common at this time. No idea what seems to be the problem, though the item loss I've experienced seemed to coincide with this "maintenance" of the auction house. Unfortunately for me, and I guess in your case, the more valuable items seem to be disappearing. Some have had mixed luck with items reappearing after a few days, others are still waiting. Best of luck.
