Its a bit hard to explain without screen shots, but I'll try.
2 days ago our team launched the rocket to space in Navera (Team 18).
We are ready to move to the next planet, however, we can no longer select any planets other than the vanilla game planets; Nauvis, Vulcanus, Gleba, Fulgora.
We can also not see our travel paths between our connected routes; Fulgoraith, Glenara, Vulsaris.
We can also not "Add space platform" to anything other than the vanilla game planets.
My friends team has just reached the rocket launching stage, and he can't make his platform above Naedris (Team 13). Also only shows his selections for the vanilla game planets.
We tried downgrading versions but it doesnt seem to have worked.

Have you updated the mod to latest version?

Yes, we were on 2.0.10. we tried 2.0.9, 2.0.7 and 2.0.6.

Swaping teams allowed us to become un-stuck from being in space. Since after launching to space you seem to be stuck, since it wants to drop you to Nauvis instead of your team planet.

From v2.0.10 you should be able to build a spaceship platform associated to your team planets (was an issue before) and see all the connections to your associated planets. After that, when you land on any of the associated planets, you merge with global force "player" so the home planet becomes Nauvis as default surface to teleport to when switching to that force via Team Manager. The tech tree and all the known planets up until that point merge and you should be able to see all of the combined planets unlocked between your team and player team.
Anyway, if you want to drop the save on my discord, I may have a look at it. PLanning on doing a release this afternoon

Hey the problem still exists i just relaunched the game and all the Team Start planets are gone and only vanilla planets exist v.2.0.14. i got this once and loading an older save fixed it but this time it did not

probaly irellevant but still mentioning i can't look at the space map where you can see all the planents and can't seem to get it back

seems that it has to do with the forced team merge into normal player i loaded an very old save where i wasn't merged with team player and everything was normal but every other save where team is merged has this exact bug

I am having the same problem, no platform can see the original team planets and I cannot see it from the space map view anymore. Only way to get back if with admin commands. It has broken my playthrough since my home base is not accessible. Force respawning on the vanilla home base is very annoying because if we die in space we are trapped and have to admin out.

This has also happened to me, which seemingly was after updating the game to 2.0.15. I am on my expansion planet Vulthera, but cannot select any other planets aside from the default ones that are part of the Global Player team. Those are unreachable. My existing platforms also only see the defaults planets but are not located anywhere near them. They are stuck where they are, so I cannot travel between any of my planets that I started on.

Let me know what I can do to help, this mod has been amazing for my friends and I but this is definitely a show stopping problem.

EDIT:
I found a solution from a discussion on a bug post on the discord server. There is a server command/admin command you can execute that will give a specific player access to specific planets. Note that all planets appear to be lowercase in the command, otherwise it will throw an error stating it cannot find the planet. This is a good work around for now, as I am back in business! I do not know how to do code blocks on this forum, sorry about that. Here is the command format and what I did that worked for me. This worked on a headless server command line, while I was in the game. The planets immediately turned white and became accessible for me, my space platforms, and my rocket silos.

/c for <PLAYERNAMEGOES HERE>, id in pairs({'planetname1', 'planetname2', 'planetname3', 'planetname4'}) do game.forces.player.unlock_space_location(id) end
