I know what flight crew berths are. They're extra crew quarters you put on your ships to provide living space for the crew of parasite craft.
But what advantage do you get for having them? Or put another way, what are the mechanical effects of not including sufficient crew berths?
I'm asking because I just realized crew berths were a thing, and I have several carriers floating about with exactly zero extra crew berths. Yet, despite this, I have found no obvious problems because of the lack.
