I just tried using FSSC to export scenery to FS 2004 ACOF. It worked but apparently ACOF doesn't want you to mess with the runways. Mine was a little bit offset from the exact location of the old one. When I created a flight and chose to start on the runway ACOF set me where the old runway was not the slightly offset one which placed me in the grass beside the runway. I got around the problem by moving the runway around so it exactly matches the original but I was wondering if there were a way to make ACOF see the new runway and place you on it instead of the old one.
Anyone have any ideas?
