I've only just noticed a strange thing while questing, if an NPC is talking through it's dialog and I turn my character around to face away but still standing right next to them, the volume of the sound from their voices dips to almost nothing like i'm on the other side of a large room, or in some cases mutes completely. I've never noticed it before until now.

I'm hoping it's a bug and not a new feature with the more recent patches because it's very very distracting. Has anyone else experienced this?
