After playing around a little, I can get materials from the Carbon Asteroid just fine. However, if I bring a Cargo Bay to the Iceplanet, the ship returns with absolutely nothing.
This could be because the Ice melts? No? That shouldn't be it. Right? I just hope it gets fixed because it seems like a bug because it claims that you need a Cargo Bay for Ice. It has happend twice and its the same issue.
