After placing 5 planets in Sol system I adjusted several planets but the adjustments don't hold. Whether I name a planet or not the game assigns my homeworld. Once it was called mars even if I had designated Earth as the homeworld. Another time I was assigned to Venus as a PQ of 4 but I had readjusted the size, only it didn't hold. Earth in all cases stands as a either a minor colony or a PQ 10 planet ready for colonization.
I'm very confused.
