Item was disappeared!

Dear admins! Need help. Today i found that my item disappeared from my bag. It was Nerub'ar Stalker's Cord it lvl 264. Character Ardagon (hunter). I think it was because of bug with change equipment manager. Pls return it. I am sure I didn't delete or sell it.

Either it will get automatically resent by the server itself in mail after some time or it's gone.
