Ouch - really really sorry to hear about this experience. I confirmed the loss. This is an extremely rare bug, that we hope to resolve for good shortly (this week). Chances are it won`t effect you again, but just to be on the safe side - try to log out to main menu and log back in every hour or two.
And check your private messages - I send you bonus codes for 20$ worth of in-game currency to make up for this loss, it`ll help you rebuild and even get further in the game super fast
