Hello there. So I've encountered this bug after my tablet frozen and I had to restart it. When I got back in the game the time from each room got messed up showing 10000+ hours until the end. Rushing the resource rooms fixed it but the clock on the radio station didn't, even after destroying the room and rebuilding a new one.
That's not right. So my suggestion is to try and make this game an online one so that the clock syncronizes with the server one and things like this don't happen. Maybe not online all the time but just at the begining and at the end for backing up just so you can play on another device. It will also prevent hackers/players from exploiting the game and change the system clock where they play just to earn awards and things...
Thank you for your time.
