I realised I have to occasionally restart the sim and console and create new flight. Mostly while operating on huge airports.
It started fix some of my previous issues like:
- AI controlled aircraft beeing bugged and stuck at the airport.
- Having zero aircraft at the airport, nevertheless how much AI traffic and AI traffic stationary percent I set.
- also if two AI aircraft gets face each other on a taxiway. One of them will eventualy de-spawn after some time, making traffic flow continue again. What also did not happen on me before.
PS: but it may differ from airport to airport. Not sure yet.
I am much more happy now.
