Confirmed. Only noticed the Major loss in the output window after I'd travelled elsewhere I'd left the escort Fampyr alone, killed Raedric, looted, slept then moved into the main keep before walking out.
Actually, there was an additional bug which I'd not seen. Durance had died, they rezzed back up like the others who had died, but their endurance stayed at zero and they didn't move.
Luckily, I was a by the doorway so didn't get a "you must gather your party before venturing forth". When the next room loaded in, all was fine again.
