I set up a mission with ArduCopter V3.2.1 over a steeply sloping field with a constant height of 10 meters and Verify Height ticked. I checked that when I cleared the mission and reload it Verify Height was still ticked. But when I flew it the height remained at 10 meters above the arming point and did not follow the terrain. On reconnecting to Mission Planner I found that Verify Height was no longer ticked. I now see that if I close Mission Planner and then reopen it and reload the mission the tick on Verify Height has disappeared
I believe V3.2.1 should support Verify Height so I can’t figure out what I’m doing wrong.
