Solved Modded van explodes at low speed

At relatively low speed collisions my van body explodes. I've never seen this before and it was working fine earlier. Does anyone know why this is happening?

 

Check if beamspring is too high.

Or change the jbeam to to a clean one from the original van file.

 

I've seen similar deformation on the official jbeam too:

 

Thats really funky. I have only had that happen once.

 

That’s really weird, I’ve never had that before. Thanks

 

Problem solved. I’d named some of the jbeam “van_bodyfacelift” instead of “van_body”
