I maybe on to something based on what you said P-D. When I generated a quadrant this time I checked my type V and sure enough SE5 wants to let it be settled. But it shouldn’t???? Time to tinker… By the way I tried it with a population limit set for gas; didn’t work. Then I tried it with oxygen and population limit; didn’t work. Then I tried it with population limit, oxygen, and top of the Stellar Objects file; nope.
