Looks OK to me.
Fairly large map, about 1/3 of the systems empty, I see Earth has no atmosphere (LOL) but a moon, and there are no direct links to Heaven
Crusied around a little and checked several warp point connections and names and they seem to match up.
Not sure what ringworld images are but I saw one nebula and one of those brown pointy things (SW quadrant). Didn't check every system but about 3/4 of them.
Not sure what else to do.
