I was finishing building it and decided to add a HUD. While I was looking for it, I also found a radar. I decided to add it too, first I installed HUD and everything was fine. Then I added a radar, but it was too small, so with the help of Fine Tuner I enlarged it and put it in the cockpit. I tried to connect it to the inside of the cabin, but it didn't work. It seemed to me that it was some kind of bug, so I started playing, thinking that when I get back to building I'll be able to connect the radar. But I immediately noticed that the loading was longer than usual. And when the map finally loaded, all I saw was the game interface on a black background. To get back to building, I had to close the application because the game did not respond to my actions. I loaded the plane but now I can't even interact with the parts! Has anyone encountered this or knows how to fix it? I really don't want to lose this plane.
