I have flown many Litchi missions and up until now they have all finished successfully. Today about 3/4 of the way through a box appeared at the top of my tablet screen that said aircraft returning to home and gave me the option to cancel. I allowed the aircraft to return home because I did not know why the return home was initiated. I have attached the flight CSV. I am hoping someone can review and see something I have not.  I reviewed and could see nothing abnormal happen between the last waypoint and when it initiated return. Help would be greatly appreciated. And yes I checked the DJI app to see if smart home was active. It was not.
