I have been using SimConnect_AISetAircraftFlightPlan successfully for a while now to control GA AI aircraft. Recently however (I believe since SU15) the behaviour of aircraft after being activated with a flight plan file appears to be broken.
The return value from the SimConnect function indicates that the flight plan has been created successfully, and the aircraft does show the correct pathway to taxi to the apron. However, the aircraft no longer follow this path. Instead they usually reverse for a few hundred meters and then take off through airport buildings in a direction that has no relation to the runway.
Is anyone able to verify whether there is a problem here?
The aircraft in question are created be me using SimConnect_AICreateParkedATCAircraft.
