This thread helped me towards the right direction.

Assertion failed: bd->position.IsValid()

I’m getting this error occasionally: Assertion failed: bd->position.IsValid(), file …\src\box2d\Box2D\Dynamics\b2Body.cpp, line 27 Context is that I apply_force to a lot of bodies to emulate the shockwave from explosion.

I believe I have sorted it out. Thank you!
