Just for reference for anyone else affected. No change for me after new patch. Instant CTD trying to activate any form of ai air traffic, real online or offline. Started this with patch 3, still same with patch 4. Lonely skies.
With the 1.11 patch, it still CTDs for me if I increase AI traffic much past 45% or so.
CTD more often since 1.11 specialy with ai traffic big airports
