Failed to load mods: Error while running setup for space-location prototype "quadromire" (planet): big-rock (entity) does not have an autoplace specification

Hmm.. What version of factorio and the mod are you using? I'm not getting that locally with 2.0.30 factorio + 0.0.3 of this mod. Any other mods installed?

I found its because I was using the all planets in one mod which seems to conflict

Gotcha.. I'll try to investigate and see after the solar system++ pack is out.. hopefully should help with this conflict (and other concerns some folks have had)

thanks, you're awesome. Perhaps make the planet a stand alone planet just added to the solar system and not one that you have to start on?

Logic for removing planets has been removed as of 0.1.0 versions. I also removed the fixed_choice from all planets.
