Hence, there are a lot of topics to backup your savegame.. Have you tried restarting the game yet?

Yes

Darn.... usually fixes a lot. You don't happen to have changed the time/date on your device?

And do you by chance have made a backup of your save?

Nope no changes and I did not back up my save.
