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.
Now compatible with some modded planets!
Not sure if it's caused by this mod, but I've never received a victory screen when meeting the victory conditions. This is the only mod I have installed.
Odd, I will admit I haven't actually beaten the game with this mod, I've only ever launched rockets / space platforms and made it to other planets, because the rest of the game wasn't changed. I don't do anything to the victory condition with this mod, but maybe it's dependent on some other factor I'm not aware of. I'll try to figure out what could be happening, but I can't promise anything.
I think what may have happened is that there was a bug in vanilla where if you went past the solar system edge, it wouldn't trigger the victory screen. Just connected the dots now after looking through some of the older posts for this mod, and I think the vanilla bug has been fixed!
