I've been trying to take police files, renaming them to police4 files, and replacing the undercover car with them, but whenever I do that the light bar always glitches out and acts weird. It has done this with every vehicle except for one vehicle that has a flat bar. I assume this is because there is no default light bar on the undercover car, but I'm not 100% sure. Is there a way I can stop the bar from freaking out or is it just a default thing? First pic is the undercover car with the flat bar, and the second is what happens with all other light bars.
