Why do some have CTDs and Others do not?

Solve CTD issues after 1.18.15.0 update & HotFix 2

The problem is caused by the interaction with the servers. I suspect the bug occurs on overloaded servers, if you experience CTDs when choosing the airport or when you press the FLY button, change the server even if its ping is worse. This fixed the problem for me even when I put real weather, real traffic and multiplayer mod.
