Mutator materials capped at the same mutation rate

[Robert Eding]

I'm not sure if its intended or not but all of the mutation materials cap at the same mutation rate: 15x.

Some of the items have mutation rates as high as 640x (MOX fuel) which just cap at 15x making them worthless when they can be crafted down to 9 small MOX fuels that each still cap at 15x.
