Hi @DensestSnail693, I believe it’s related to blackshark ai as per other posts here…so yes, not 3rd party, it’s in the core code. I reckon some small bit of code is off and only used for particular scenery where these crashes are occurring. I tried to place exclusion polygons in a custom scenery, and even tried to overwrite an airfield (OPRQ) which crashes immediately when you approach it (even in Dev Camera mode), but still could not get it to work - so there is something fundamentally wrong in a tiny piece of code that is used in a few small places. I’m hoping with every Sim and World Update that it is fixed since you can reliably reproduce it, but alas, it’s not a big enough of an issue and needs far more voting up.
