A few weeks ago out of nowhere I could not sneak kill anyone. I play with a xbox one wired mini controller and when I push the Y and B button in stead of killing with the blade of woe it does one off the attack that are bind on those keys. I bought a new controller and it still does it. I tried doing it on the keyboard and still same thing. I repaired my game not long ago just to try it and it stil no change. It starts to get frustrating because I can't do any brotherhood quests now.
Is someone else having this problem? And have you found a fix?
