Newton2 - heightmap + vehicle = penetrations

[Aphex]

Moving over to the heightmap collision, I've noticed that my custom multi body vehicle penetrates it in places (mostly where the slope is steep). Seem to be a few holes in there, though the debug render appears to follow the drawn mesh perfectly.

if you place another body will teh body go trhought?

I'll try later tonight. I did think it was that problem from the other thread (opposite diagonals) but there's definitely something odd going on, as the vehicle tyres can shake and I sometimes get large forces that kill my object suddenly when intersecting.
