Some CMCs Missing from Populations List on Commanders Window

In my game I have 18 CMCs.

In the Commanders window, with Civilian Administrators selected in the bottom-right pane (and anyone in the list clicked on) and Populations selected in the bottom-center pane, the list of available assignments is missing three CMCs.

I suspect (but am not certain) that the missing three are all on bodies which I had previously placed my own colony on (and later removed).

DB is attached.
The missing CMCs are:

Huang Mining Corporation (ZZZPrime III)
Terblanche Minerals Group (Abacus V - Moon 12)
McNay Resources (Baal-A III)

Hi all, I've been an occasional player of Aurora over the years - sometimes invest a lot of time, then don't play for years. I last played in 2021 and was on version 1.13 (just prior to v2 I believe). Basically I invested a lot of time in a game on that version and rather than start again I was thinking about going back to it - my question is, how much am I missing out by not upgrading to the latest version?

Cheers

Hey, about a month ago I was just like you!
From the time C# dropped until right around the time 1.13 came out, I put in thousands of hours of playtime.
And I just recently got back into it, with 2.5.1.

You are missing out on quite a bit if you don't upgrade.

I actually went through the changelogs first and wrote brief notes about the major changes, to help me process it all.
There's a whole lot to like. Not just new content, but also plenty of QoL tweaks that make a big difference.

I highly recommend making the jump.

Space stations, the advantage is that they don't use shipyards, the drawback is that they can't be refitted?

Another advantage is that they don't have armor, which makes them lighter and cheaper. (And also, obviously, incredibly fragile in combat.)

You can use shipyards to build stations if you want to, subject to the same size and tooling rules as regular ships.
In fact, I like to build my 25k freight barges and 100k colonist pods in a shipyard--and I can actually build either one with the same yard.

You can also, of course, use such shipyards to refit stations if you like (again subject to the same rules as regular ships).
But no, in the absence of an appropriate yard, a station cannot be refitted.

Another minor drawback of building space stations with surface facilities is that you can't use any component stockpiles to speed up production.

On the Wealth/Trade tab of the Economics window, income and expenditures are broken down by type.

I think I understand that "Tax on Shipping Trade Goods" is the income I receive from the civilian shipping lines when they haul a shipment of trade goods from one colony to another.

But what does "Tax on Exports" represent?
I would have thought that it represented income from shipping to other races (NPRs), but I have only encountered one NPR, and we aren't trading. (They refuse to communicate and I haven't discovered any of their colonies.)
Besides, I was receiving this Tax on Exports income even before I encountered this NPR.

In any given year, I usually make around twice as much on this Export tax as I do on the Trade Goods tax--but it varies.
