(id:2786457) There is some random pressure. I tried to get ride of it with 0.00 temp pumps, but that didnt work... Someone, please explain! It was going so well until the stupid pressure thing happend!
You do have some elements that make pressure, mostly the portals.
But the main reason the save acts like that is because gravity is off, which puts it in zero gravity mode. Everything floats with even the slightest pressure. Go into settings and turn that off.
