Start on any of the first three planets: Vulcanus, Gleba, or Fulgora.
Choose your planet in the startup mod settings before starting a new game.
Compatible with many modded planets!
When attempting to start on planet Cubium, I am hit with error
Failed to load mods: cubium/cubium.lua:11: attempt to index field 'molten-iron' (a nil value)
stack traceback: cubium/cubium.lua:11: in main chunk
[C]: in function 'require' any-planet-start/data-updates.lua:40: in main chunk
I think that's an issue with Cubium, not this mod. I don't handle any compatibility for custom planets, that's managed by whoever made the compatibility.
