hey, i love your game. Its very fun and might i say, a time waster ;). My question was if i would have to start over my old city with the new update. Ever since i updated, i have not been able to.
Sorry, you can't use the old save file. In additon to bunch of new data in the file, the game balance and features where changed in a way that your old city would not make sense in the new version, if it worked at all. I will try keeping breaking changes like that to minimal in the future.
