I finished all of North America and Europe.Spent a lot of time in the game... even paid for no ads... then the game needed an update so I updated it. My progress in terms of generated coins and upgrades was there, but the maps were unaccessible... after several restarts I was still unable to tap on the buttons to try to unlock something. So I decided to reinstall the game... And now I have to start all over again and all is lost. Basically I wasted time of my life that I cannot get back... ggwp
