Show unique zones or another turfers zones, restart app.

I'm running Android beta 2.2.4, but this is not a new problem. If you show unique (white) zones, and restart the app, after the restart you often see a mixture of white, green and red zone. I guess this is due to slightly too heavy caching. The same thing happens if the display of white zones is zones owned by another turfer. My workaround is to toggle unique zones back and forth.
