Items not sold from AH, simply disappeared ?

Hello,

I have been noticing something weird with my account. Not sure if the warmane staff are actually doing something or am I bugged ? or am I simply getting old to remember anything ?

Basically, I put items on AH to sell them, next day I login to collect but there is no mail coming from AH and my items are not showing on Auctions tab either. Meaning they were not sold and they expired but didnt come back to me. They simply disappeared.

Anyone experienced this before ? is there something happening I am not aware of ? I just want to know for sure that I am not crazy!
