Boy, PAQ, you certainly get the maximum value out of MOI - all of your models are HOTT! ;-)

I was getting this previously but had pegged it down to geometry that I had >mirrored< that would cause things to disappear.

Michael, (hopefully) fixed that for us with that quick patch he put out.

If you didn't mirror the piece that's causing the disapperance, then it must be something else that causes a similar kind of error within the model?
