Literally just doing the Cistern location and the Tangle is all we need. You can leave the other places untouched, mainly because y'all didn't make updated versions of those. But, if I can take a seat and be the armchair developer here, it can't be THAT difficult to swap it in, given your talents. The overgrown, refreshed Nessus environment is TOO beautiful to leave with Echoes. It would build player sentiment and faith. It would evolve our universe. It would make the world feel alive. I don't think we really have that many campaign beats that take place on Nessus anyway, so re-assigning waypoints, public events, fetch quests, lost sectors, etc, wouldn't be too grueling a task. But we need this guys, especially for when we do get the eventual quest to head over there again.
