AH bug (or feature)

I purchased an item (Hunter 4 shard) for $3k off of the auction house at around 11:36 CST today (1/27). My inventory was full of stone at the time of the purchase. I thought the item would go into the collection bin or some other storage location while I cleared my inventory, but apparently it just disappeared into the ether.

Here's a screenshot of the AH purchase titled 1137buy.JPG and a screenshot of my inventory after I stacked the stone together, entitled 1138noitem.JPG.

I would appreciate any assistance you can provide.
