Two of my itens went missing after i logged out

Hi, today between 15:00pm and 16:30pm i bought Vengeance Bindings and Spiked Titansteel Helm from the auction house, it cost me almost 2k gold for both. Soon after i equiped the itens, bought a blue stamina gem for the helm, equiped it and logged out. After i logged in the itens are no longer in my character, mailbox, rebuy vendors or bank. The gold still gone but i dont have the itens anymore.

I apreciate if the moderators could help me.

ask around if other players had a similar issue.

Theoretically there is no support for this kind of issue but you may open a ticket in-game for an official reply from a GM
