Realistic car controller + driver problem

Hi guys I hope it's the right section for my problem. I use realistic car controller for my cars and I would like to add a driver in the car. I created an empty child in a car and added a driver's fbx. Once the driver is positioned in the car, I realized that driving the car if it crashes into an object, the driver disappears and positions itself under the road. I noticed that if I remove the damage to the vehicle the problem does not occur. Does anyone know how I can solve? thank you

 

Sounds like to should email the developer. They are quite supportive as long as you purchased their asset of course.
