CalculatingPi

I have the same problem. I haven't played in a while but hope to use my existing game in progress. If I start a new game, it looks like it will work but I can't choose the characters in my stuck game. I haven't played since before the iOS upgrade. I did see that I needed to verify that Gamecenter was logging in - I did this. If I erase and reload, will I still have my in-progress game?
