OMFG!!! I went to the market. Then i clicked "deal finder", to buy something cheap. I found an "acid torso" and i bought it, but it doesn't appear on the deactivated items! WHAT DO I DO?!
I think you purchased an Acid Ghost instead of an Acid Torso. According to your transaction history, you bought one recently for 300 TC. And you do have one in your inventory.
