I had an unusual thing happen the other day and I'm wondering if it's a bug or intended behavior. I took off from the top of a building which was 80 feet tall. I then flew to another location and decended to an altitude of -50 feet (50 feet lower than the takeoff altitude). I lost signal at this point, and the inspire went into failsafe RTH. However, instead of climbing up to the RTH altitude (I have this set to 60 meters), it flew straight home (and almost crashed into a tree . Since I have my RTH set to 60 meters, I assume it should have ascended to 60 meters above my takeoff point first before coming home, but it didn't do that for some reason. Could it be that the higher takeoff altitude confused it?
