So I feel like I must be the only player to encounter this edgecase, but while attempting to collect the second message on the 6th step of the Rogue Network quest (the one next to the brig in the parkour after Raneiks), I died before collecting the message but after having correctly shot all of the panels. The message spawned, the hud showed the waypoint and everything, but once I respawned, the message was gone and so were the operator stations and shootable numbers. No amount of dying, reloading checkpoint, or even starting new runson any character has been able to get the puzzle to reappear. I even tried letting a friend lead the fireteam to no avail (they had completed all but the mega puzzle and on previous runs with them had puzzles from steps I wasn't on appear throughout the dungeon). The only thing I have yet to try is getting someone who is also on step 2 but has yet to do the puzzle and running the dungeon with them, however, none of my friends are still on that step, and LFG has returned little luck either.
