"What can I offer you? Absolute control over everything by owning the machine, Teamspeak, and all other services so I can rip the rug out from under you from whenever I want"
I have no info about that, however there is a 'fix' for it. After player enters a vehicle you have to set that vehicle.invincibility to false (you gotta do it clientside as .invincibility is not implemented on the serverside api yet) and the vehicle will start getting damage like it should.
