Ok so heres my problem. i made a custom model for a warthog. i currently do not have the collision model set up for it yet, but i can still get it in sapien and compile the scenario just fine. when i load up the map with this vehicle, it works exactly as planed in terms of driving it and shooting its gun (although the gun can only shoot facing the front of the car at the moment). but real problem is when i exit the vehicle, i get a second of my guy jumping out then an expection error. What could i have done wrong that is causing this error?

And it did. Thank you.
