There has been multiple reports on the
Air 2 giving the homepoint updated message mid flight for no reasons but the actual home point memorized by the craft stayed unchanged. This is the latest report on the issue :
RTH UPDATED concern. I believe the same has happened to your drone.
As the drone landed onto wet sand at maximum forward speed in the previous flight, it is highly unlikely that it has landed safely. Furthermore you have lost view of drone at that moment because it has descended below the point you were positioned, you could not have initiated another takeoff just a few seconds later. Unless there are more data, I am still of the view that the previous flight did not end in proper landing but crash.
