Crash on start up

Game was working fine last night, but now won’t open. Shikudo screen appears, then the app “closes”. It is still viewable running in the background, but if you try to renter the “open” game, it just shows you the Shikudo screen and crashes again.
Updated to the latest version and the problem persists. Have restarted my phone (iPhone 5) a couple of times and the problem persists. Hope this little glitch is sorted soon! Real shame something seems to have happened overnight.

It sounds like you might need to uninstall and reinstall the game. Did you save the game with your Game Center or a Kongregate account? Reconnect to the third party account after reinstallation will help you get back your progress.
