Hello,
we have a problem with people mounting on drivers seat even when forbidden in the config.

"Prevent other players from mounting vehicle": false,
    "Prevent mounting on driver's seat only": true,
    "Prevent other players from looting fuel container and inventory": true,​

The fuel config works but not the "mounting on drivers seat".
Is the config wrong or is there a way to debug?

Ok i have found out.
The "Prevent mounting on driver's seat only" is only active when the "Prevent other players from mounting vehicle" is set to true, too.
