That's where I've been running scans. It seems the missions are kinda few though. I may get anywhere from 2 or 3 to no more than 5 or 6 and no amount of board hopping or waiting or re-logging lets anymore appear. I've taken all the missions available, and waited as long as overnite and still no more until I comlete the few it originally gave me. I've also done enough already that I'm allied with the controlling faction and they are really the only one that's giving any missions at all. The other factions might pop up with 1 extra scan mission from time to time or a donation mission. The only thing that shows up pretty much is donation missions until I complete the scan missions it gives me. I go and do those and as soon as I scan the datapoints at the first outpost it completes all the missions. I do get quite a few mats sometimes but so far no Adaptive Encryptors. I just fly back and turn them in, then I'm able to get another handful and rinse and repeat. I know it's pretty much up to the RNGesus as to what I get out of it, but these have to be the hardest mats I've tried to get. They are also the last group I need to do all of my planned upgrades on my ships. I only need 7 of the stinkers so I had hoped it wouldn't take that long. But alas, it's taking me longer to get these than about all of the others put together it seems!

Good thing is, since I started back to playing after Commanders, I've had a blast unlocking all the engineers/ plus by gathering all these various blueprint mats I've really enjoyed playing all aspects of the game that I probably otherwise would never have done much with. I don't think I had ever drove the SRV until I had to gather mats. Now I've gotten pretty good with it and never use drive assist on it and hop around all over the place like a dune buggy in the desert!
Thanks Cmdrs!
