Is this (or similar other) bug(s) still an issue for anyone?
Using the latest patch as of today (beta 5.3 I believe), with verified game cache in Steam, I saw this when changing frequency of Stars (not planets):
Small Map, Tight Clusters, Abundant Stars: 26 total
Small Map, Tight Clusters, Occasional Stars: 28 total
Even with random numbers, this is a little wacky.
OK, so I tried again just to get more examples and find a different issue as well: the map is not random.
First--Small, Tight, Occasional: 28 stars
2nd--Small, Tight, Abundant: 28 stars in exactly the same spots
I remember reading about this on the forum a while back, but cannot recall if it was addressed yet.
