Logged in, missing items

I logged in this morning, I left the game open in what i assumed was a safe place but when logging in all of my tradable items were gone. i'm pretty sure i wasn't killed and lost them as all my emeralds and ingredient's are still here, any idea what could have Happend? i don't have the money to replace the stuff i lost yet as i'm only lvl 54 :(

 

How much soul points you have left? Were you afk in Olux? It's not a safe place since some mobs from a quest area nearby always escapes and attack players in Olux. Please do /class before afk in dangerous area or go to a safe city before afk such as Cinfras.
So thought I can't log on right now I can give you some emeralds to recover your lost later.

 

I had all 13 when i logged in, and I was afk in the jungle village upstairs in a house, which seemed pretty safe. and that would be so amazing i have 36 Eb to my name now ;-;
