Body Armour Disappearance Issue

Bu report number:1.794.633.160

I bought a 'Morior Invictus Grand Regalia' body armour via trade a few days ago and was working on its sockets to get +5% to all Elemental Resistances. However, when I logged into the game, I suddenly noticed that my Morior Invictus Grand Regalia body armour was missing. I tried relogging, but it didn’t come back. It cost me 20 Divines. Please check what might have caused this and if there’s any way to recover it.
