I killed Mephisto and afterwards there was the quest point to talk to Neyrelle. Unfortunatly, during this talk the game crashed. After restart I spawned in a city and the quest book tells me to use portal at the mirror edge. However, when I go to the end of the grave of Akarat I can NOT enter the dungeon of the light to go to this portal. Neyrelle is with me but I can not talk with her (Eru is already gone). So how can I progress the quest to finish the campaing.
I am really sad about this, please help.
