I'm assuming this is from the ES2 beta because I've heard people talk about it, but the spaceport's description is send to colonized planet instead of colonized star system.

I don`t see the problem? I`mean "planet" is just more specific, yes you send them to a star system but usually you want them to land on a planet and not to fly circles around the sun.

Because you can't select a planet, only the star system

I see - not that I care that much if it gets changed or not but it only says that the population gets send to a plant, it doesn`t say you can choose. So your description would be more accurate.
