When I place an oxygen collector, it does collector, but it says it has no power, I've hooked up steam engines to it, works now. But, here's where i'm confused, when I try to place an oxygen pipe, it does not attach to it, or the distributor. Does anyone know how to fix this, i'm playing single-player. If anyone knows a fix, please tell me.... I want a dang moon-base. Also, does anyone know why it never closes when I click "save and quit." I can fix that, but I would like to know why it does that.
