So i will start out by saying that i had built a proper oxygen setup and went to the moon. all fine and dandy. after being on the moon for a while i decided to see how quickly i would die without my oxygen gear on, so i took it off. i didn't get any invalid oxygen setup warnings and i don't take any damage. nothing happens its just like regular day on the overworld. my server does have a lot of mods installed. are there any known conflictions with other mods that would cause this problem? i've searched through the forums and have been unable to find anything on the matter. i'm running a forge 1.12.2 server.
