I notice that while all cars spawn with the Native Trainer mod, some dissappear within seconds after spawning. I don't know what is different about these cars. Maybe these were cars the devs planned to add to the game, but they didn't get the code for the car's operation completed before the game's release date, so they despawn simply because the incomplete code for these cars glitches, and the game prevents an all-out crash from the bad code by instead despawning the car with the bad code?
One of the cars with this problem is called Prototipo. It looks really cool, so I'm not very happy that it isn't working. Can anybody here recommend a fix for this car (as well as all the other ones that have this spontaneous despawning problem)?
