| Also, just curious, why is there a glowing ring of some sort around a planet sometimes? I assume it's because of something I've done. I see it on Mars and Earth off and on. |
If the ring is blue, it means you have selected the planet in one way or another.
| after I built my last needed freighter, the starport kept building them. |
Once a Starport completes a ship, it will continue to build them until you tell it to stop. You must select the planet, or colony manager screen, go to the build ship menu and then select nothing to stop building ships.
Most people want the starport to continue to build ships throughout the game and it is easier to allow the ships to be built automatically, then going to every starport, every time you want to build a new ship.
Example, many people build defending fighters for near orbit during the first few months of the game. (Tiny ships, all weapons, no engines, not meant for space combat.) Instead of having to go to the planet every time a fighter is completed, which could be once every one or two turns with some Industrial planets, they just let it run and within a couple months they upgrade the ships and move to a new build.
There may be an option to disable this, I am not sure because I have not had the need to turn it off.
Hope I have been some help.
