I seen a lot of people having this bug, me included. Maybe Larian already knows about it, maybe not. I want to share some details.

The bug is a exclamation mark above Wyll's head that just doesn't disappear after talking to him or long resting.

- Note that is triggering the bug is: "Missive from Moonrise"
- Note is found on the Monastery Map.
- I have done underdark + some Act 2 content before going to the monestary.
- Since I already got the information that the note is supposed to reveal in Act 2/shadowlands, I believe that the bug might happen because you already had the dialogue tree with wyll about the information the note reveals.

That is all.
