What do I need to do to start the quest "A New Order"
Please help, and thanks!
Weird. There seems to be more and more of these "rare bugs" cropping up on SSE.
By "restarting the game", you mean loading a save from before entering the castle? If not, try that.
Well [censored]. That's the second game-breaking bug I've read about today, both of which were already known on the UESP however. What next I wonder...
I suppose Erzherzoghan's advice might help however. Could be mods.
As annoying as this is, the only other option I see is to restart the entire quest. :/
Galling.
Maybe try waiting 30 in game days maybe in a inn at Whiterun and then try again to see if you can get the quest active.
Do you have a game save before getting Serena. Sometimes guest glitches out and the flag is not completing correctly
