Aylin problem after killing Lorroakan

[mukoviscydoza]

I was doing the Night Song quest in Act 3 and decided to lie and tell Lorroakan that Aylin is dead. I succeeded and went to camp to takl with Aylin. I went with killing him, went back to the tower, talked with Lorroakan with her there and started the fight. It was weird because she just stood there and wants in the fight with me, but i continued and killed him. Now she's still standing there, I can't talk to her anymore, she won't go back to camp and even had a problem with me looting the tower. In the quest log it also says that the quest line is finished.

Unfortunately I also forgot to save the game before the fight, so loading the last save will take away progress that I don't want to lose. Does anyone know if there's a way to fix it?
