I've been trying to figure out why some of my airports were missing buildings or having elevation issues after updating to the new installer. For the most part, with the exception of Las Vegas, all my airports are back in good shape again. I discover that not only did I have to install a full GSX wrapper, but most of my airports too, with the exception of JFK. After doing just that, but for FSDT and FLIGHTBEAM airports, my scenery is showing up again, and if you are having elevation problems because you use Orbx like I do, try to manually disable the scenery with their vector configuration tool. That worked great for FLIGHTBEAM KDEN. For KLAX, all I had to do was re-install a fresh wrapper, and everything was fine. Las Vegas I did the same thing, and now I have the airport on level ground and all the buildings are there, but I'm still having elevation issues with the outskirts of the airport, which seems to sink in block sections as I'm coming to land or take off, and when I'm just sitting at the airport, the outskirt Orbx scenery is higher than the airport towards the east side of the airport. Getting closer to solving the mystery! lol
