Starsector 0.97a is out! (02/02/24); New blog post: Codex Overhaul (05/11/24)
except for Duzahk that can spawn good planets.
It isn't a scale from 0% hazard to 100% deadly, 100% Hazard Rating is the baseline value. You'll see values from 50% to 250% in the outsector stars.Now, if you're not seeing values from 50% to 250% in the stars outside of the established core and everything everywhere is 100%, then you should post a bug report in the bug reports forum, with a copy of your save file.
Am I supposed to be able to colonize the red dwarf in Ta'xet, because I did. It also only has 100% hazard rating. And nothjng else.
