Cars crashing server

I have noticed that and custom cars I.E tdm sgm etc… will crash my server when players are driving them usually only when they hit a curb or they handbrake im using a custom gamemode any idea as to how to fix this?

Which game-mode are you running? That crash occurs when the tire materials aren’t set up correctly ( since the beta, all materials needed to be set up at once, in one file supposedly ). ubertire, etc won’t work, you can revert them to jeeptire and they’ll be fine.

“material” “jeeptire”
“skidmaterial” “slidingrubbertire”
“brakematerial” “brakingrubbertire”

etc…
