Are you saying these models worked in official POV? Because by
rights they probably shouldn't have. Meshes never used to be
reliably usable for CSG other than unions because they had no
well defined insides and outsides, and if differencing other
shapes from them worked at all, it proabably acted like clipping.
MegaPOV changed this by giving meshes "insides" so differencing
from a mesh will behave in a fundamentally different way in
MegaPOV, but that most likely isn't a bug you're seeing. You
might have to substitute clipped_by for difference to get the
same effect now.

Is it fundamentally different from when you do the same difference
of a box from a regular sphere primitive? If not, what you're
seeing is the difference "solid" meshes (new in MegaPOV) makes
on the operation.
