Yes, that's the one. And that's the exact recommendation I found in an old reddit thread when I researched this. I don't quite remember what we did it for, but there was probably a reason.
We are part of a clan, fortunately, so I guess we can pop in sometime and get it. I feel like such a leech for just getting blueprints from them and not interacting with the clan itself in the slightest, but from what I've heard, most clans don't complain about that since they know that a clan is just a means for an end in the end. Still feels a little scummy lol.
Gladly! I'll send you a friend request :)
