The perk in Sneak that makes me muffled does not seem to work. If I am wearing DB shoes, I see "Muffled" under active effects, and enemies won't hear me/detect me as easily. if I remove the shoes, I do not have "Muffled" under actice effects, and enemies start looking for me much faster, because they hear something.

I have 100 sneak and only using light armor, mostly DB shoes but also other light shoes, but only the DB shoes are viable for sneaking as of now.

And, the Silent Roll perk seems a little bugged. With weapons sheathed I can only roll once per button press, on L2, but with weapons un-sheated I can continue holding L2 for a constant rolling. For me, IRL, it would probably be more easy to constantly roll with sheated weapons rather than holding them when rolling. So I believe it's a bug. Either it's holdable or not, I should not be able to hold the button down only with weapons raised.
