I played the game a third time now, learning the mechanics. I noticed that the pressure in my asteroid drops with time, and even with 12 electrolyzers the atmosphere got so thin with time that the plants did not grow anymore, and the Dupies were dying from starvation and suffocation. Before they die they make it really hard to keep everything going, their high stress level makes them attack the hamster wheels, batteries and food sources permanently.
Losing the atmosphere seems to be my biggest problem here, I do not know how to avoid that. Is there a kind of material that sucks my air away? In my latest game I was not even that far, about 14 Dupies populated the place.
I attached the latest savegame, it's a desparate place, half of the Dupies are already dead.
Steps to Reproduce
Hard to say - take a look at the savegame and tell me where TF the air is gone.
