Description of the issue:
I keep encountering a problem with oxygen and trees. I simply cannot place leaves in space and because of this it is impossible to start oxygen collection in space. I've looked through the other issues and found something similar, so I turned off hardmode in the config and I still can't place saplings or leaves on the moon or other planets. I don't know if this is just me being idiotic or not, but I would like help, please.
