Last night I managed to get into a region with a friend and spent a considerable amount of time building a city. This has been my best city/region to date; we have even almost completed our first great works!
My issue: I got a message notifying me of a need to "roll back" my city. It forced a restart on my game and I have been unable to reenter my city or even claim another city in any other region on any other server ever since.
What I would like to know: Is there any hope of me ever getting back into my city that has been "rolled back?" It is very disheartening to think that I will have lost such a promising city that I put a lot of time and effort into, but what is even more concerning is that I would spend an equal amount of time on a different city just to have it stripped away like this one.
