[Bug 933220038] cannot acces endgame

Hi !
i have beaten Doryani in act 3 cruel. I spoke to him in front of the portal with a cinematic launching. I am currently in the zingurat refuge. I have exhausted every dialog of Doryani, but still have a quest asking to speak to him. If i try to open a map, i get a message telling me that i cannot access endgame.

[EDIT]
I have restarted the game and redo the fight against Doryani. I still have the quest but i can access the maps now.
