I'm pretty new to the game. I've been playing for a few months now. I'm currently trying to get engineering done to my ship by using Felicity Farseer who requires "Grid Resistors" for the 1st update to FSD Boot Sequence. I've looked online and read that Grid Resistors are a "very common" manufactured material and can be found in Unidentified Signal Sources, Ship salvage (Military & authority ships), as well as Mission rewards. I've NEVER seen one as a mission reward and I've investigated DOZENS of Unidentified Signal Sources of all kinds - mostly Degraded Emissions and I've NEVER come across these. I thought they are supposed to be "very common". Can someone please give me some guidance to find these? I'm tired of scouring the galaxy looing for these. I've been all over and still no luck. Thanks!
