I think I broke Lord of the Hunt...

[Resus]

The situation is simple... I killed 4 beastmasters and started the mission for the 5th one (ghoul lover). I fought with him in the cave and after he left me there I encountered him outside... And then game lost it. At some point during our battle I was near death in a QTE fighting off a ghoul. I succeeded... but I thing game somehow thought that I died and ended the quest - there was a message that beasmaster survived. Unfortunately, before I could do anything a ghoul killed him... And game didn't recognize this as completing the quest.

So now the quest is locked (it says that I need to complete more Torvin quests... however there's none left) and the beastmaster is dead. Is there any way to fix it? Maybe somehow reset the whole progress in the DLC?

you can make a new save slot in the main menu and do the lord of the hunt all over again. you wont lose your progress in maingame/other dlc's, its just a different slot.
