So I got back to town after going through the tombs, and I had a bunch of stuff to sell of the AH. After I put up all my things, and paid the transaction fees, over half of the things I put up disappeared. No money is in the moghouse, it's not up for sale, and it's not in my inventory.
Is this normal? Has this happened to anyone else? How do I fix?

Your items are there, you just can't see them. The AH listing only shows 7 items at once. If you go to the account section at the top of the page and log in, click your character, and go to the AH tab, you will see all items you have listed for sale.
