I think I have narrowed the CTDs for me down. Just flew one of my best flights ever in this SIM. Flew from KSTL to KATL using RexWeather Force2020, SimTool Kit Pro, Imagesim KATL,Navigraph and Pushback Helper ALL active and working on 2 Monitor. Not a single problem but the TOO Talkie Talkie ATC.
Crashes are happening with FlightBeam KIAD and Cloudsurf Asia Simulations WSSS. Something that these too have in common are causing my crashes. Happens in other places in the world but these are the two airports I purchased last.
