I have confirmed at Alcaire Castle (on PTS) that the invisible enemy issue is present in the new build.
I have opened a ticket against this (140605-001000), I have experienced this a few times now on this build (including one specifically where I was attacked by an Orc at a mine and then when passing by the same mine later was attacked and no visible Orc was present.
I've not run into this on the live server in a very long time; so anyone else experiencing this?
