Was trying for a gleba start (because i make bad life choices) and even after crafting far over 10 nutrients to unlock the biochamber, the biochamber is not unlocking. the research is at 100% progress, but still shows at red in the tech tree, and no biochamber.

I am using a variety of other mods, unsure if one of those might cause this.

Have you checked that the other prerequisites for the biochamber are unlocked? And if there aren't any, you may be using Discovery Tree, which I have seen multiple people have issues with.

Derp, i did not realize that the "achievement" sciences would still have prerequisites, funny the things you miss even after a full playthrough.

Making sure to have mined a jellynut as well as a yumako opened up the biochamber and it has now been succesfully researched.

Thanks for the mod and the response, we recently used the mod for our lan party and it was really great that we actually got to see the other planets in our 8 hour Lan instead of just nauvis once again.

Nice, glad I could help. Also, awesome that you used it for a lan party! I can't imagine having a space age lan and then not actually being able to go to any of the other planets.
