Corrupt/missing textures in one of my AI Models? I only use default AI Models.
And what difference does it make ? Do you think default AI models and textures can't go missing or be corrupted ?
Missing/corrupted doesn't necessary mean they have been released as such by the developer, they might simply gone missing/corrupted on *your* system, for any number of reasons, including file system corruption.
You said with AI at 0% the crash doesn't happen. This clearly indicates the problem lies with one of your AI.
As I've said already, you can be easily mislead thinking FSDT JFK might have any part on this "because it doesn't happen on the default JFK", but that doesn't mean anything: the two airports have different parking assignments, different parking codes, different parking radiuses and even the number of parking spots is not the same, which means you will NOT have the same set of AI (even if all other settings are the same), and if the problematic AI is not showing up at default JFK, you'll have the wrong impression this might have anything to do with FSDT JFK, but it doesn't.
