Using Lifesupport and Spacebuild

Hi, I’m not sure if this is the right place to post this.

I’ve understood that Life Support and Resource Distribution adds the need for oxygen, water and pressure in spacebuild gamemode. Well, I’ve downloaded these three (spacebuild_v3, lifesupport2 and RS2), but when I select a spacebuild map (I downloaded gm_new_worlds2), change the gametype to spacebuild and enter the game, I can just build a spaceship and visit arctic/desert/lava planets and open space, no need for oxygen. What’s wrong?

E: Realized this wasn’t the right place to post. Apologies!
