Why does my virtual world go bad?

The virtual world changes to the better or worse based on the completion of activities and challenges on your Do Good List.

susGain defined an expected completion time for each activity. If that time has passed and you have not completed the activity, your virtual world in this area/colour will change for the worse. If you complete the activity, it will change back to the better. The world may also change to the worse if you accepted a challenge and did not complete it in time.
