I've build airflow tiles but gasses get stuck in the wrong places anyway:
- Hydrogen gets stuck in my coal power generator room.
- Oxygen gets stuck in my oxygen generator room.
- Oxygen gets stuck in whatever room I transport it to.
- Hydrogen gets stuck in barracks, making it hard for dupes to sleep.
There's almost no natural spread of the different gasses, it's almost like I have to build gas pumps in every room. This makes no sense and I haven't see it in other people's bases. What am I doing wrong?
