Is there /absolutely/ a requirement to have the barrels mod as a necessary dependent mod?
I'm looking to run the 2.0 update without Space Age (I haven't done a full play-through yet) and was curious if that would break the pack as a whole.
Yes, because the fluids may be used in different planets and you can't ship these fluids. The barreling mod does nothing else then enabling the recipes that are already invisible in the game.
