I'm having that same Wyll "!" bug for a few days now, but I've also noticed that lately none of the other party members have exclamations at camp. Gale, although he has been in my party the entire time, has nothing to say other than "I do enjoy our conversations" for several days now, although he did suddenly tell my PC that she's hot mid-battle a few days ago. Nothing else to say since then, even though the story has been quite eventful. That's not like him.
I fear this play-through might be broken, and I'm considering going back to an old save and branching off to see if I can snap them out of it. The game is still amazing, but I feel I'm missing something without those party dialogues.
