Basically, I'm looking for the details of using the quest commands. I'm stuck on "Build power and core components and connect them." (You know what quest that is if you're far enough.)

I've built everything, but it isn't detecting it somehow. I tried using /completestage, assuming that was what I needed, but it did nothing. Is there something I don't know about the command? Should I just use /completequest? Will I get the quest reward if I do that? Which quest is it? I used /questlist, but I don't know which quest it was, unless it's the final quest.
