Whenever I try to spawn at an airport, I don't get an option to spawn at a parking space like the terminal or anything. This is happening with all of the airports, by the way. This only started happening today. I've tried choosing different planes but the option to spawn at a parking space just doesn't show up.
If it matters, I'm playing on an iMac Mojave, and on FlightGear 2020.3.11.
