While I was playing on S2:Courage that whenever I would sell items on the marketplace, my total; cash, capital, and cost of goods would update to the new total but than after one second the total would reset back the the total before I sold. I would lose the items I sold back to the marketplace and receive no reward.
Earlier today, I transfered to S3:Gunland. At first, the marketplace worked fine. The totals all would update, and stay at the new amount. But the bug returned. I attached a video to help you identify and possibly fix this bug.
