Visit Pelagos, an insular planet of coconuts. Use calciners to refine resources, and unlock cargo ships as the perfect way to connect its scattered shores
I'm using "Organized Solar System." Pelagos overlaps with Corrundum even with "Cosmic Social Distancing" installed. I'm guessing it's because there's no connection between Corrundum / Pelagos.
Not sure the issue would be present with other combinations of planets. Would it be possible to add a Corrundum connection to fix this?
