No i found several special planets i couldn't settle on because of the extreme condition. But the three i refer to are normal planets, no info on them at all. First i assumed i had missed something but third time I kinda figured I'm stuck at 4 for whatever reason. Is there some tech i need? I kinda rushed the settler ships to get as many planets as possible. And i don't seem to have governments in my version.
And i didnt notice any votes on anything. I am playing multiplayer with my gf in a team, were only on turn 60 or so. If that could affect it
