I'm having the same problem. I don't believe it's recognizing me as being logged into Origin, and thus not saving my cities. I've started 5 cities so far. The first two crashed after about 15 minutes and didn't save any progress. The other three were tests to see if I could get it to save, varying from 5 to 15 or so minutes, all of which I exited using the escape window, and none of which saved. I really hope I'm just doing or missing something stupid here, I've been looking forward to playing this, but can't play due to crashes and saving issues.
