…is choice paralysis. I have not played in the last couple of days just because I can’t make up my mind about what to do next in a section where two quests are happening the same place and I don’t want to risk screwing them up. I can’t make up my mind and just commit (I’m being vague because I don’t want to risk spoilers for Act 2).
I’m actually in the middle of the gauntlet of Shar rn so I’m not sure how that plays out, but I did already rescue everyone from moonrise. Avoiding spoilers - there’s a potential interaction in moonrise that sends you on a mission to the gauntlet anyway, so I may backtrack to moonrise if I were you.
As for the Crèche, that’s technically part of act 1 and I did it before coming to the shadowfell. No idea if you are able to go back and do it after going to act 2, but if you are able to, I recommend it.
