That generally was the case earlier (and in Betas too), but in this specific case, the CTDs are definitely not coming from AI traffic. I have it disabled for months now and still had my first CTD yesterday. Ground aircraft/vehicles/staff always set to 0 as well.
Another streamer I was flying with on Friday had only multiplayer aircraft on, no additional liveries, set traffic to generic and still CTDed.
This is clearly not the casual CTD occurrence where old suggestions might work. This is something different.
