I had 2 Emerald Whelplings (battle pets) up on the AH now one of them is gone. I have no idea where it is. It is not in my pet journal, it isn't one one of my other character's bags, it is not in my mail, and it certainly isn't in the bank.
It's just gone, 5k flushed down the drain.
What the hell happened? I've never had this situation before. I logged out and in in case it was some graphical bug - nothing.
