I made a brand new RP-1 express install through kerbalism. I researched crew survivability that allows me to add oxygen into service modules, but when I try it simply says 'no tech for oxygen'. I tried searching the internet but to no avail. I reinstalled the whole RP-1 express install, but still no technology for oxygen apparently. Oxygen doesn't exist in capsules as well. What do I do? I can't progress whatsoever
