I bought a guild vault yesterday and all 18 items I put in it are gone as of this morning. I have a log of the items being deposited and no log of them being withdrawn they just disappeared. I had a guildie put something in the vault and take it out and it showed both the deposit and withdrawl of that item. I tried to report this elsewhere but thought I would post it here as well.
Update. I put some trash items in the vault to see if Blizzard would steal my stuff again and sure enough this morning everything gone no log showing withdrawls.
