RTH at night

[oc1doc]

My first night flight with my Air 3s went fine except for RTH. I was about 1/4 mile from home at about 200 feet altitude and hit RTH. The drone seemed to be struggling to decide what to do, would fly toward home a short distance then increase altitude multiple times until it was approaching 500 feet. I cancelled RTH, flew to just above home and then hit RTH again and it landed OK. Not sure why it was confused. I had RTH set to "Optimal" and home point was recorded normally at take off. Anybody have a similar experience? I assumed that if visual wouldn't work well due to low light then at least GPS should guide the drone home.

First off, your ceiling should have been 400 feet.
Second, the obstacle avoidance should have been turned off for the RTH since the drone can't see obstacles.
The drone OA needs to "see" to be able to detect obstacles. Without the contrast of light, the drone may have been "seeing" lights and darkness as obstacles.

This is just a guess based on what I've read.
