The Galactic map shows a blue ring around the Tau Ceti system. The "Planets" display says there are 3 worlds there with a suitability of 2 or less. The "Main" display shows 3 worlds with a Col Cost x2 or less.
I can find only one.
On the System Generation and Display panel (the F9 page) I see a binary system, with Tau Ceti-A and Tau Ceti-B.
Around Tau Ceti-A there's a world with a colony cost of 0.12, and I've settled it and renamed it Tau Ceti Center. That's the one I'm able to find. Of the remaining worlds listed on the Tau Ceti-A tab, none has a colony cost less than 6.24.
On the Tau Ceti-B tab, theres one with a colony cost of 3.0, one 56.2, and then a bunch of N/A.
On the "Options" tab, asteroids and moons both have "Show" selected, and the "Minerals" box is un-checked, so I can see bodies that lack minerals.
Switching instead to the "Available Colony Analysis" page and I sort by system name, un-check all the boxes on the right, and set the Maximum Colony Cost to 3. Two Tau Ceti worlds appear on the list, the 0.12 and the 3.0 mentioned above.
All these views are taken with the default Human species selected.
Anyone got any idea what's going on? Am I maybe misreading one of these displays? Am I getting the wrong idea about what the Galactic Map means when it paints a blue ring or counts the worlds with Colony Cost of 2 or less?
