This never happened to me before. After landing, I went to lunch without pausing the simulator, leaving my Piper in the GA parking area. When I came back, a Cessna was taxiing towards my plane; it parked beside it and let the engine run for several minutes. Then, all of a sudden, it disappeared. :o
I'm not really sure why I'm posting this, as it's obviously an unimportant glitch with no ways around; perhaps just for a laugh ;)
