I'm a bit confused trying to attach any of the fuel or battery components of the mod, or any of the other pieces that are "half sections" of the other parts. My problem is there is only one attachment point on these part, and it doesn't allow for proper alignment with say, the mk2 habitat module. Like shouldn't the two half parts attach together to make a whole and then be able to attach to the other full size pieces? Am I missing something obvious? Does this question even make sense?
