Vehicles Are GLITCHED On Server, HELP

Ok, I put some addons on my server one day… The next day, all the vehicles were glitched. By glitched, I mean you cant sit in them. If its a car, and you try to use it, it makes the noise, but nothing happens. I uninstalled the addons, and am still trying to fix it. Does anyone know a fix for this? Or do I need to reinstall the normal vehicles, or what??
I dont know the file location for the vehicles, so if I need to reinstall them, please give a link and a location for them.



Which vehicles are not working? Or is it all of them?

EDIT: Woops, haha I rephrased that sentence and didn’t fix it.

All of them, turned out to just be the gamemode… v_v
