I have a big base and alot of air leaks so more often than not when i return from my resource hunts my base is always like out of oxygen but i came back plugged up all the leaks and no oxygen was coming out of the air cleaners i used an osygen tank to make sure i just wasn't using it to fast but still no oxygen at all please fix this glitch because it is hard to keep going past day 101 on survival mode without any oxygen in the base
Was your oxygen going down or just not going up?
That sounds very similar to what I found over here with oxygen levels getting stuck in certain situations (https://itch.io/post/94395)
Stepping outside for just a second should unstick things for you in the short term if it is related.
