Hello --
I use an iPhone 4 running iOS 7.0.4
Game version 2.1.6.3
I opened my store this afternoon and had several sales. I picked up my sold items and got the cash. I started to set up new sales and the game paused, then rolled back. All the old sold items were there. I tried again and went through another rollback. This happened a few more times and the final time it appeared that I didn't get the gold for the sold items. They were gone, but the money from the sales wasn't there. It's possible that I had already gotten the money and saw a double credit during one of the rollbacks, but I can't tell for sure.
