Well, that's a toughie. Unfortunately, the real-time engine in Virtual Villagers is very complex (much more complex than Fish Tycoon) and relies on the accuracy of the system clock. Game play becomes very unpredictable when the system clock is adjusted. You could wait it out and see if the game recovers, and start another game in a different slot while you're waiting. Or you could just delete the malfunctioning game and start over.
