I read before that I am supposed to kill Raedric a second time as undead if I killed him before.
So I get regular "undead attack from Raedric's Hold" at my stronghold, I figure, alright, it is time. I go there and...everything is normal.
I am like oh well, and yesterday, I complete the game, and the ending is like "Raedric came back as undead and started a reign of terror etc"..
So I check on internet and found that a "Frightened Villager" in the Celestial Sapling inn, is supposed to give me the quest but...He is not there!
It seems my save is bugged and I can't get the Champion of Berath quest, even though I keep getting attacked by Raedric undead minions.
