Whenever a user purchases a car, it's not owned by them, it's owned by the state so they can't lock it up or keep it for next time they log back in. Another problem is they can use the car purchasing command anywhere without having to be at the car dealership.

I'm currently using Raven's Roleplay 0.3c Gamemode script, why are these problems occuring?

You can fix it , by making your own roleplay.
If you decide to use Raven's Roleplay, I think you should ask it inside that topic, or post the script here, because I can't help you without a script.
