I got a decent roll of 51% at Farseer which gives me a jump range of almost 60 ly and applied it (Anaconda). I noticed I still have 12 units of mats for another try at a better roll but can I go back to Farseer and try again or is it a once only thing and I have to store my engineered FSD, buy a new one and engineer that in the hope of a better roll?
