I'm pretty sure that's just a matter of configuration, e.g. see Advanced-Rocketry/AdvancedRocketry#933 (no idea how up to date that still is). Either way, this is not a problem on our side because vanilla doesn't have a concept of oxygen in dimensions.

Aha, I found the issue, thanks for referencing that one as digging into one of their world files showed that Advanced rocketry added the same Dimension ID as a moon (20) As thats what was causing the issue with no oxygen. Seems fixable by just changing the setting in xml file and reloading though, thanks again!

Alright, no problem!
