The audio when standing a 2nd floor of a watchtower (With no 3rd floor) makes the audio sound as though you are below a roof, whereas when you place a roof or 3rd floor down, it changed and sounds as though you are outside getting hit by the rain. Have tested this multiple times and different ways. Server is NA 8519 1st Person Only.
This also happens on the 1st floor of the watchtower, audio sounds as though there is no roof when in reality there is.
