I can't figure out how to unlock the other 3 planets. I am producing the new white pack and have the new lab unlocked. However, any of the tech that just takes both whites won't let me pick it. Is there a pre-requisite required that I am missing or am I misunderstanding this? I tried to also move the new white packs to my main base with all the other tech and no change.

Unlocking Nix, for example, requires space and nanite science packs (the two white sciences). You'll need to use the new Lab, which usually only works in low-gravity, to research with a nanite science pack. You might need to have a microgravity lab already placed down to select that research. There are no additional prerequisites other than the nanite science pack itself. It could also be that there's a bug with another mod you might be using- if you post your list I can try to take a look.

Ya it's gotta be a tech mod issue then.

When I go to pick a tech in the new lab, it just opens the tech screen which doesn't let me pick anything :|

That's a lot of mods! Too many for me to reasonably dig through. We can try some initial troubleshooting though.
Can you select the research from the button in the top right? can you see the research for Nix in the tree (screenshot it)? Do you have any mods that modify labs in general?
If you can try disabling mods individually, I'm suspicious of qol_research, some-autoresearch, simultaneous-research, and gleba-lab

Ya I get it. I love mods haha and always go crazy. You should see my skyrim lmao.

Anyways, I disabled a bunch and all of those mentioned and nope. What is the pre-req's for the techs that just cost the whites? Like the basic module productivity? Also what is the name so worst case I can use the console command to just research it if I have 2? I tried every name I could think of and none of them worked.

I'm having another tech related issue with the Maraxis mod as well :|
