I have a very strange problem since updating Aerofly FS 4 (Steam version) with the networking function.
All the aircraft at any location (parking, runway) do not move anymore on the ground even with full power. So I cannot taxi or take off anymore (yes, the parking brake is off).
If I choose a approach location or anywhere in the air, the airplanes move and behave absolutely correctly. Then I can also land on the ground but as soon as the aircraft stops, it will stay there and I cannot move it anymore (even with full power).
What could be wrong here? Any ideas?
