I had the T2 as a base and LS rover. I needed to change the battery so I ended the base and changed the battery and started the base back up. Never touched the base tripod or T2. When I checked my check point I missed it by 0.12 ft. Any ideas? First check shot was 3 min Boundary point and open sky. I checked a few other points I had on the first session and missed them by the same 0.12 ft.
