I remember a thread about how quickstart does not start Desert Homes with all of their extractors. I could not find that thread to see whether a developer had responded to it. I assume it is a goal for you to start with all of your extrators regardless of how many minable asteroids there are around your home planet if you have started with quick start.
This hasn't been fixed and I couldn't find a thread about it (maybe it has something to do with search not working).
