Hm, the working theory looks fine, but what happens if I also put an extraction site next to the refinery hub? Will the orbital / surface port economy be refinery or extraction?The working theory on how you get a refinery is to have a colony- style outpost/ coriolis/ orbis in orbit of a body that has surface sites... you then put some refinery hubs down on the surface and it influences the orbiting facilty to get a refinery economy.
Edit: on outposts... it's important to note if what you're building has "facilty economy" or "system economy influence". Outposts just have a facility economy, so that's only on them. They may be influenced by hubs, but i need to test that more.
For outposts, that may not be the case. After putting an asteroid port as primary, I deployed a research outpost, and my system economy went from extraction to extraction hi-tech. Sadly, I am not able to check the goods in my primary port after Thursday update, since the medical installation that I built later is blocking my asteroid base entrance
