Many of us know of this, but I am specifically calling it out here so the Dev team sees it. I am sure this impacts the General Aviation AP (nose dive) and Garmin (blank screen) issues (and others) that populate this forum and the general community.
If you fly with AI GENERAL AVITAION TRAFFIC DENSITY slider to any setting other then zero and USER GENERIC PLANE MODELS (AI TRAFFIC) is off - you will get random items changing, turning on and/or turning off when you are in a certain distance of AI GA aircraft either while in flight or on the ground. I believe that is true especially if the AI GA aircraft is the same type as your aircraft.
