I have no idea what caused the second crash but suspect it has something to do with the first crash. Perhaps the debris that was caught in the guards.
I've flown numerous Litchi waypoint missions. What really caught my eye was the wind on your coat when you were attempting to bring it home. I'm guessing 15 MPH? It's my experience that when flying Litchi missions in the wind the aircraft is challenged to maintain its course between waypoints. And that and flying near obstructions at 30 MPH.
The other thing is the elevation you were trying to fly. If you take off and hover at head-height and check the elevation that your machine thinks it at, then fly off a hundred yards with some elevation change, and then return and hover at head-height again, you'll see that the craft doesn't think it's at 6'.
Anytime I program an "iffy" waypoint mission in, I'll do the test flight in a conservative manner with my left index finger ready to abort. Keep in mind you're using a map that's created from a collage of photographs taken over a year ago and then stitched together with software (thus the coordinates can be a few meters off). And the vegetation is at least a year older. If fact, I don't see the white observation towers that your bird didn't hit in your mission map.
