Comment (by Atul Kedia):

Thanks for that.

For the record, Presync enabled gives the following error:

Required read for SPHERICALSURFACE::sf_area[0] (rl=0) not satisfied. Have Nowhere and require Everywhere missing Everywhere at the start of routine CarpetMask::CarpetSurfaceSetup. Current valid state:
Valid entries: SPHERICALSURFACE::sf_area[0] (rl=0) Nowhere.

Looks like an easy fix. I have no experience with both this thorn and presync to know how that can be done.
