Exploding jbeams help (Devs Needed)

My school bus explodes on a hard impact and causes ---> instability detected - turning off physics, the problem seems to be located in the front portion of the bus, I have tried to find what jbeam file is causing the problem. Most of the jbeams are from the semi.


How do I track down the problem. I can see that the afyp node is blasting off into outer space along with some of the frame nodes and the front bumper is acting a little weird, but are those the nodes causing the problem? BeamNG doesn't outline the cause.

 

It has to do with beamdamp and beamspring most of the time, play with it a little and you should see the difference.
play beamng in slowmotion and have beamvis mode at stress

 

ok thanks im going to try that

 

I fixed it by setting selfCollision to true in all jbeam files but it killed the framerate
