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 starting on a planet besides Nauvis, the "Orbital logistics" simulation in "tips and tricks" crashes. It is likely somehow caused by the default import location of items changing from Nauvis to the new starting planet.
I opened that tip in my game and I don't get a crash, though it's still broken since the rocket won't send up the belts.
Do you have any other mods on?
I tested with PlanetsLib as the only mod enabled (even without any modded planets), and the simulation still crashes, so that's definitely where the bug is. The changed default import location was just a red herring.
