First of all i would like to say thanks for porting this great engine to XNA.
I'm in the middle of developing a car game (like all the others on this forum it might seem :)
and i'm experiencing some kind of bug.
When i have multiple cars on the track and they collide, sometimes given the right conditions (which i can't seem to figure out exactly)
the engine get's alot of NaN vectors, and the game hangs / stops to respond. This might not be what's causing the game to hang i just find it quite strange.
Any help would be appriciated!
