Might just be mine, but RV (east) does not appear when running in appropriate area's. Map stays in RV (west), and your pointer showing your loc dissapears when running in RV (east).
For some reason when I go to the EAST side of the map it does not show up. The west side does though. Moving from the west to the east just shows my arrow moving off the map and then its gone. Never flips to the east side of the map...
Also, my arrow was a little bit off. For example when I walked on the road, it would show me off the road slightly.
