The Search quest

Hey,
i'm on the step of "confront Kanu and the First Herald".
I hill the Herald but i died in the last skill he made ( :( ), and now the step seems bugged.

The next door are not opening and the boss disappear.
I've tried to relog/respawn/quit the game .. same issue.

Anyone have the same problem?

edit. i opened on the poe1 forum :\ was poe2.
