I've just played around Sacred Stone in the EE and came about Bruthor the orc in the immaculate jail.
Well, aside from the strange issue of him attacking me when I open his door while the guards are still alive, he also won't recognize if I free him via teleport, despite him asking me to do so (after I've killed the guards, obviously - they didn't react very friendly to me opening an empty cell).

It seems that bug has been around since before the EE (although I don't remember what I did in the old version).

Any ideas?
