Baermar’s ugly sweater is currently buggered.

So for some reason, the ugly sweater somehow makes you make no noise when doing any action. This includes breathing, screams, injured grunts, falling noises and so on.

What’s happening, from what a friend has told me, is that the game is weirdly thinking you’re Aestri and not Baermar when you have the Baermar sweater equipped; but since you don’t have her voice lines loaded in since you’re playing as Baermar, it can’t get anything and you become fully silent.

And you can’t really do anything about it, you either run the sweater and be fully silent or you don’t run the sweater.
