[ODE] QNAN in Body position! May be LCP problem? Need Help!!!

[Joe Ante]

Hi,

Ive seen that problem too. Its not something I have been able to reproduce
and it happens very seldomly. But sometimes when driving over our terrain or
even over a normal boxcollider with the car, which drives perfectly stable
otherwise, the rigid body positions sometimes just become NAN.
