Tried to use the bug report form, but it keeps saying I filled it out incorrectly ...
When picking up the letter from the dead zealot of the absolute on the monastery trail, I run into a bug with Wyll every time.
It doesn't matter if I read the letter, or Wyll reads it, he says the line & I say it back, and he gets the exclamation mark above his head.
However, the conversation it denotes does not trigger.
Based on others having the same issue with this trigger (as well as a couple others with Shadowheart elsewhere) in a few Reddit and Steam threads, I did try a full rest in camp (after also reloading to duplicate the bug).
Nada.
The exclamation mark disappears after the rest, but as soon as you talk to him he has only his basic line again, no conversation about his father, and then the exclamation mark is back above his head.
