I've just made the mistake of overwriting my engineered FSD (50Ly jump range) AspX with a poorly-considered re-roll, thinking the "every upgrade will be an improvement" feature had been implemented (I've just returned from a Sol-Colonia-SagA trip so my brain is a little mushy). How long before I can rectify this mistake without hunting for another batch of Arsenic, CMs and DMWs?
