I completed the main part of Halsin's dark curse quest. The log says he is grateful and will help me. Further, before I deal with Keterik, I definitely need to run to the Mountain Pass and help Laezel, otherwise she will leave. Three of my other characters have already quietly reached the 3rd act in this way.
However, with the release of the new patch, Halsin now walks away from me if I go to the Mountain Pass. Moreover, in the dialogue, he says that he will wait for me in the Shadowcorrupted Lands. He will also be in the camp if you return to the Shadowcorrupted Lands. But the task now displays as if I did not even undertake the quest to remove the curse!
I'm afraid to go further so that the game does not break even more. My friend, who has been going through very long and thoughtfully and has reached Act 2 just now, is complaining about the same problem!
