Without checking further. My guess is that you're talking about edicts there for the campaigns.

So there should be another technology or tradition which gives access to the heathcare or recycling campaigns.

Yep I'm talking about the edict.

When I take ecologist & libertarian ethos I do not have access to healthcare and recycling campaign.

There are not other technology that provide those edicts. I really believe it's a bug

The bug is : when you chose some ethos (like ecologist / libertarian / spiritualist) you do not have access to those edicts.

I have started a game with the following ethos : industrial/materialist/elitist I had access to the 3 campaign after researching "planetary unification tech"
whereas when I started another game with ethos spitualist/ecologist/collectivist/xenophile I only had access to the education campaign and not the 2 others.

It seems that selecting some ethos when you create a new species prevent you from having access to those campaigns. It's really problematic because the ecologist faction requires you to do a "recycling campaign" but I cannot do it cause I don't have access to it.

Plz help developper :)

I have the same thing in my game where I have a faction that wants healthcare subsidies but there is no healthcare campaign. I console commanded the research_all_technologies cheat to see if it is in a later tech but it is not.

I figured out what is going on. The recycling campaign is only available to Industrialists and healthcare campaign is only available to Individualists for some reason.
