@Algonquin1234 that wasn't the solution sorry.

btw, I replaced the crusaders in game with humvees then the same thing happened: the natural spawning crusaders are now trying to move but they can't lol (again, just like when you are in a car then you press w and s at the same time). thoughts about that? I really think that what happened to the police vehicles in the game are related to this because I also tried to replace the police cars back then but decided to bring 'em back.

@mrwallace888 nah, only simple trainer

Whenever there's a police car that spawns chasing some car, that police mobile can't move. I mean, you know when you're in a car and you press W and S at the same time? that's what happens to that specific police cruiser which is weird. I hope somebody can help.
