It appears that the needed components for the Rare Reactive Core side are swapped. I currently have the Core Uncommon and no other components. I select Reactive Partial Core Conversion as my Target and it tells me I need Genomic Analysis, Supercharged Cap, and Semi-Conscious Energy. If I select Total Core, Waterworks tells me I need Bio Goo, Genomic Analysis, and Supercon Membrane.
These are backwards. In game, Total needs the Semi-Conscious and Partial needs the Membrane.
