This warning is coming from the pfdGeoBuilder(). It has different limitations
on its tesselatation then MultiGen does.

It's probably a 4 sided polygon that's not coplaner. Typically these polygons
occur in the walls of areal culture (tree blocks) where there's a change in
direction or the wall in conjunction with a change in slope of the terrain.
In MultiGen, search for faces with 4 or more vertices and choose isolate
select. Next, check all those faces for coplanerity with zero (epsilon)
tolerance. Triangulate the faces that fail the test.

Nope. The pfdGeoBuilder doesn't give a loader any feedback wrt this failure,
other than the pfNotigy and the pfdGeom structure doesn't have a name field.
Regards.
