Unity 5.2.0f3 Triggers Broken??

The function OnTriggerStay no longer works if it is parented to a Unity Car prefab. I have a system of triggers that detect if a car is taking damage that all use OnTriggerStay, and while this was fine in the previous version of Unity, now the trigger does not function while parented to the car. If I unparent it from the car it works again. Any ideas why? OnTriggerEnter still works but in my situation OnTriggerStay is much more useful. Is it a physics setting?

I ran into the same problem 1 day ago.

Here is the solution or work around that does work.

In any script attached to your parent Game Object put an empty OnTriggerStay function.

That’s it.
