I’m playing on European server DE 3930

I was drying off my gear in front of a pub fire, I un-equipped them when stood a little bit away from the fire, I stepped forward to put some steaks on the fire, stepped back and everything had vanished.

Backpack, Jacket, Vest - and all the inventory

It could have vanished as soon as I took it off, or after I stepped away, I’m not really sure.

Is there anything I can do or has this gone forever?
