Is he a part of your island's /coop?

 

Nope, no one on my coop, just me. It was definetely a hacker.

 

Just to add to this, I was there about to buy the dia, then he just burned to death and nothing was there, idk what is going on but there are more than just him who have this happening to them, I just don't carry good items on me now, just to be on the safe side, the /warp skybase really needs fixed

 

This has been resolved now. I've refunded the items.
