Help !!! Item missing

On night on 30.12./31.12. I equipped Leggings of Woven Death on my Warlock which were tailored by priest on the Horde faction of Iccecrown realm. They were traded directly not via inbox .When I logged fue minutes ago my Leggings of Woven Death were missing from my slot. I cant find them in bag nor in inbox.

Can someone explain what happened, anyone have experience with this kind of problem?

Go to bank and open it, open character panel (by default 'C'), mouseover pants slot press and hold 'ALT'. Can you see your pants on the list? If not, you have to get a new pair. Could check your priest and see if the pants are still on that character for some reason.
