Fractional research facilities is quirky, but not a real issue.
Fractional ship components is more of an issue. Because you can disassemble a fractional ship component, and get a NEGATIVE fractional ship component. Then you can disassemble that ship component, because it thinks you have them, because you HAVE negative ship components in the colony stockpile.
You can keep disassembling negative ship components until you have a huge number of negative ship components. And then, if you decide to scrap them, because the notation is untidy, you LOSE transnewtonian elements. Which is proper, but amusing.
