So I downloaded a few models I love and replaced them in open IV. Well nothing happened. So I tried with a regular car, and it worked fine. So I went back to the cop cars and removed the files and readded them. I rebuilt the file and hit exit, went ingame and got a cop car. But they are still the default cars. So I got new models and still have the same issue. Its only with Police2 and Police3, police just changed without an issue. Anyone know what I'm doing wrong or if I have to do something else?
