Another possible bug with nightmare song

I was defending the spire while Zaelfar and a few others were raiding. I attacked him at the judge and he fled. So I head up to the spire and summon him, get slept yada yada. I don't know exactly what happened while I was asleep but the judge never died and they were able to walk right to the inner guardian and attack him. After waking up I checked to see if the judge had died. He was in the courtyard, not the Foyer. All were able to freely walk past him. Eclinsan was there as well, so I can only assume the nightmare song caused the judge to flee as well. When it did he no longer protected the spire. Any other questions let me know.
