Tesla navigation will save a pin exactly where you dropped it, and navigate to it, for a few days, maybe a week, and then automatically moves the pin to some random nearest address. This changes where the vehicle navigates to on FSD to THE WRONG LOCATION, usually not even on the right side of the road. This bug needs fixed. It has been like this for a long time, maybe always. Pin was placed on the star, and saved as a favorite. The favorite automatically moved to the X. This bug is reproducible.
