I enter Blind Cliff Cave, Melka talks to me, I free her, she gives me a tour, I follow her, we enter the final room, Melka yells at Petra, we kill her, but the quest doesn't complete, the marker is left on her corpse. Even if I reload to a save before I enter the cave and try again, it happens either way. I noticed there was already an issue regarding this quest, but that was for killing Petra before freeing Melka. I am confused since I am doing everything in the right order. I have a save, but I don't know how to share.
