I noticed that in some cases I'd removed all the oxygen breathers from oxygen planets, leaving only 1 or 2 million none breathers. What then happened was the computer started treating these planets as domed colonies Now I have funky planets with 18/3 facilities.
you mean you already had none-breathers on your planet and it wasn't a domed colony? That is a bug, the only way not to have a domed colony is to have only one type of breathers on the planet.
