V3.03 Update just released and it includes this bugfixes:
1.) Planes now with taxi lights when they are active (Night Lights are on)
2.) Area smaller again that planes also will get spawned on busy airports
3.) better route following - that also VFR flights get little closer to their routes
4). smoother approaching . planes come closer to the ground (edited)
5.) FSLTL Liveries will work!
The ground teleporting will be fixed when Asobo will repair the Ground-Waypoint-Function! Sorry for that!
