284 polearm gone

since the update the 284 polearm of my hunter blueskyz is gone which was in my inventory previously. i got several items sent per mail which caused problems equipping but my polearm was not in the mail. how can something like this happen srsly??? i demand a replacement, you can check my 2,2k 3s achievement and or a backup of your database that you hopefully have! i already made a ticket ingame but i do not expect a reply to it as i am aware of the inexistent igame support.

open a ticket in game, you are not the only one who had this kind of problem after the Core change
