"Atziri's Temple -> Infinite loading

Hey guys!

My problem: After defeating Doryani in act 3 he will "try out something" on to the temple console of the vaal ruins. After this dialogue, when trying to enter the instance, I get stuck into an infinite loading screen.

Is this an actual bug? Does anyone know a solution for this?
I had not found any solution for this when researching for a possible fix/ solve. Neither did I find any ingame dialogue option which could maybe solve this issue.

Thanks for any incoming reponse!

bump!
otherwise this league is unplayable.
