Description of the problem

Well I was on the moon of an Earthlike planet, the moon had a tiny bit higher gravity than normal Earth, so basically Earth gravity. There was atmosphere but a tiny bit, only just barely purple. What I was doing was just making a dome to be a moon base but as soon as I put oxygen in any oxygen vent the game would just crash.

Old AR version. Update to the latest beta

Ah ok

Oh the game just crashes on the latest version when I start the game. Gonna continue using the old version
