@EJNorth Thanks for the video, and thanks for stopping it before any terrible fate met those giraffes
Well, as you might have noticed in your video, the airplane seems to bounce off invisible landing gear, and we see a commensurate dust cloud behind where the gear would be. This is obviously not what you should be seeing, and it's also something that I test with the "colliders" have to place for the aircraft's fuselage to collide with the ground. This leads me to believe that something very strange is happening on your system where the gear are somehow deployed, but not visually deployed. I don't know where to begin on recommending troubleshooting, other than usual "empty your community folder", if it's even something that you want to get to the bottom of.
