Hi James,
Thank you for waiting, we finished checking your flight logs. We were able to see the sensors were working properly, the unit was responding to the pilot's commands and the motor pods were al working properly.
When Solo entered Follow Me mode, it started following the Pilot's location and, from what I can see, a vehicle was used and Solo kept following. The reason it didn't come back is because it crashed before doing so. The pilot lowered the altitude at which the Solo was flying to about 13 meters, after a little while, it seemed to have crashed against a tree from what the coordinates are showing.
Since the incident wasn't caused by a malfunction, we're unable to cover the damage under warranty, I apologize. I hope you were able to retrieve the unit, let me know if there's anything else I can assist you with.
Best regards,
