No matter what i do i cannot close or demolish any medium gates.
I have tried disconnecting them from Commercial flights and then leaving the gates for several days so that whatever scheduled flights could be cancelled or removed - yet i still cannot close the gate as there are apparently still flights assigned to this gate, despite being not available to commercial flights for about a week.
Tried deleting taxiways and nodes to the stand; the aircraft simply taxis over my terminal when i do this. also tried to dismiss aircraft from the gate but this doesn’t do much at all.
Someone please help me with this. I have 10 stands and am trying to delete two of them to make way for a new concourse.
