I'm wondering why Rubia was chosen as one of the planets moved out of the Nauvis system? Rubia has several technologies and a science pack that depends on imports from Gleba (Bioflux and Iron Bacteria). Without installing the RJDunlap planets this massively increases the distance spoilable resources need to be transported to reach Rubia. (Which was previously a neighbor of Gleba) I'd prefer not to need to install the Quadormire just as a source of Bacteria and Bioflux in Miara since it doesn't have anything new.
I guess an extension of this question, for the planets that were left in the Nauvis system, why were they left where they were?
Thank you for your time.
