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!
Started on Fulgora and cannot fly to other Planets. They are all researched and I got the Master of Fulgora. On the Space map i can see the other Planets, but there is no connection between them, just between all the other planets.
Can you check if the space connections exist in factoriopedia? Also, what mods are you using? I haven't had reports from anyone else about this happening, so I'm thinking there has to be some sort of weird interaction going on here.
The connection in factoriopedia is there. The Mods are an good Idea, thought about that, too.
some checking later:
the reason was the "delete-planet-compatability" mod which I had enabled for some unknown reason. Without it works. Thanks for your help!
