I can't send a colony ship/base to a gas giant or asteroid belt even if I have learned Orbital Habitation. Are these expected behaviors?
The existence of "Orbital Habitation" probably wasn't considered, but asteroids and gas giants are supposed to be uninhabitable now
for humans (and likely various other species).
I'm starting to think more and more that outposts should have species associated with them, as there's a lot of content that seems to rely on them, and it will require quite a bit of effort to make sure stuff doesn't seem broken.
Old content is going to have to be rewritten... It's unavoidable when adding and reworking game mechanics. There are properties of planets, ClockwiseNextPlanetType and CounterClockwiseNextPlanetType, which don't presently have parsing, but will soon, which could be useful for less automatic terraforming implementation, and which don't depend on a particular species.
Regardless, I'm inclined to leave these issues in v0.4.1 unless there are major objections.
