[WotLK] Bags deleted

[Dingdong]

Just logged into my rogue, and the bag in my first slot + all the items in there were deleted.
I've heard of this happen to one person in my guild, as well as a person just now in a RDF group. The first time I heard of it, I figured it was a hacker. However, I think this may be a database issue if it's happening to multiple players.
