Thanks. I also got some info from dugi and while I was not able to find any code where vehicle component objects (1000-1193) are created using Create(Player)Object, I think I greatly reduced the number of times I get this crash by removing AttachPlayerObjectToVehicle-related code. I may be doing something wrong in that code...

Now, however, I get something with an exception at address 0x006FA915. This happened just once though, but the previous symptoms are all the same - some chat spam warnings...
