If you have Reddit accounts, give this guy an upvote - https://old.reddit.com/r/MicrosoftFlightSim/comments/iw6mis/plane_exorcisms_or_how_i_seem_to_have_reduced_or/ - he’s the one who found it but I wasn’t sure what he meant by “Ground Traffic”, I initally thought he meant cars. It was only through trial and error that I found it was the Ground Aircraft that was causing it and they are actually stationary parked vehicles, although still seemingly with conflictable instruments.
I’m guessing the sim is prioritising you, then when it loads the vehicles in as you move, it starts prioritising them instead.
