My name is Dragonforged and I got this game little bit ago and one day I had one lazurite and then the next It was gone. I had made a offer of trading one lazurite for one rainbow jar but when I looked at my warehouse It was gone! Am I a noobe and does the item disapear when you put it in a offer at the trading tab.

When an item is placed in trading it does become invisible in your inventory. If you cancel the trade, it will reappear in your inventory. This is just so you don't accidentally use the item or money you are offering on an trade until it is over.
