AI: NPC ships crash on planet instead of landing when timeacceleration is active #4931

Observed behaviour

Ships crash on planet.

Expected behaviour

NPC Ships land even when time acceleration is active.

Steps to reproduce

start at mars
speed up simulation by 1000x or 10000x or something
a lot of ships which should land on earth explode, this is clearly visible in the console with messages like "QK-2445 destroyed by Earth, status:inbound ship:lodos, starport:Torvalds Platform"

My pioneer version (and OS): git 20200718 linux

Looks like this class of problems may get attacked with different handling for out of sight (OOS?) handling similar to what the X series is doing. The responsible codebase is out of reach for me for now :( , but it's a "fun" issue.

NPC AI problems are known, has been reported multiple times before

NPC behaviour is a wide topic :) . I was a bit specific here with the time acceleration. Maybe it's a problem with the physics too, can't tell.

This specific issue is that Autopilot/AI is likely to crash ships during "rendezvous" with space stations in low orbit.
