I'm not sure if this is a bug, oversight or intended.

When having both this mod and your N.tech mod installed at the same time, the research for oxygen bottles get pushed from automation+logistic science to chemical science.

Oh, Im looking into that

Its not a big deal since you can modify the amount of starting bottles. Now defaults to 50, which should be enough. Of course this is a mod whose intention is to harden gameplay.

Your update to the N.Tech mod fixed this and made oxygen bottles available with automation+logistic science. :)

I do have some suggestions to maybe make the mod more balanced and interesting micro management/production. If you're open to that.

Of course, just tell me
