Arwen, I'm having the same problem as Whale. I received an e-mail telling me I'd had a sale on the Marketplace, but I noticed my In-World Cash amount hadn't appeared to change, so I went to view my Transactions, and there was nothing there either. I'm ashamed to say I have no idea where to report a bug, so if you would be so kind to walk an old timer through it, I would be eternally grateful!
