I have been playing quite a bit with the 64-bit client since Dark Brotherhood and the v2.4.6 Update was released and I don't know if this bug occurs on the 32-bit as well. The bug is this, a large frequency of npc's now look either straight to the left or right when in dialogue, so you see their face in profile as you would normally look them straight in the eyes. This is not a serious issue but I thought I would bring it to light as I could not find a thread about it anywhere else.
