Rotating Project North doesn't rotate all geometry

Before

and after:

The elements that didn’t rotate are the more complex geometries

I think I see what’s happening. The only elements that rotate are seemingly the mass and its associated geometry.

R.i.r. Doesn’t know pbp has been rotated… but that can be fixed?

Around which point is all the mass geometry rotating?

There is an existing report with Autodesk concerning this topic.
