Chocolate box keeps reverting back to bronze level. I had finished the first task of the gold level and was working on the 2nd. Next time I opened the app (after only about 30 minutes) it was back to bronze. I should have had 2 days to finish the gold and got only about 1 hour. My app is up to date, no new updates since…
I just had a similar problem and spent gold bars to get a UFO. The program got hung up. Now it's working again, and the gold is gone, but I didn't get the UFO.
