No, it's due to the fact factions no longer send you to repair other faction's bases. So if one faction has a base that needs fixed, and 9 other factions are within range, the odds of a mission is now 10x lower.
I've been wondering if this is the problem too. It's now very hard to find a restore mission; I'd say too hard. I'm not sure why other factions giving you a mission to an abandoned base was a problem, after all there are plenty of ship missions where one faction will send you to deliver something to another faction, so there's no conceptual reason why having two factions involved should be a problem.
As it is now I still haven't seen a single one pop up. If this is the problem then the only way to find one is be lucky enough to dock in a system with a faction that has an abandoned settlement, or to find such a settlement first and then go looking for a station. And there still does not seem to be any way to identify an abandoned settlement from the system map (something that was suggested during the alpha). Nobody has time to fly to every settlement to see if the lights are on.
It's even worse because, apart from basic fetch quests, these missions are one of the few types you can do in settlements that do not have to involve combat or breaking the law (or both). Not all of us wish to be forced to play Billy the Kid or Wyatt Earp in space.
Making them vanishingly rare has detracted from the Odyssey experience; certainly they were pretty much the only missions I wanted to do. Without further explanation from FD, this particular change does not seem like it was necessary.
Yep, I found both damaged and functional ones. I may have been lucky for the couple of functional ones I got to find though.
I think I've had only one functional one that way and a whole lot of degraded. There's been a couple of occasions where the SRV could see there was a power regulator but that part of the crashed ship was embedded in the terrain and there was no way to get to it.
I did waste one of the few I collected powering up an abandoned settlement (pre update 5) to loot it, then stepped out of the building and the settlement wasn't so abandoned any more, which ended badly.
Honestly I was finding it more reliable to get them as mission rewards, until all the restore missions I enjoyed vanished anyway.
