Strange Giant Car Crusher Bug

The car was supposed to be crushed up instead of reappearing like this.

 

This is a bug with not only the car crusher, if you have a impact hard enough you can get the game to lock up, press J to pause physics and the press it again, I think that's how you fix it, the game pauses physics when it detects instability (why I don't know, ask a dev )

 

It's not just that. The car is bigger than normal. That's not right. It didn't just freeze the game. Something else is happening.
