Vaal Templebug, unable to unlock atziri's chamber

Hello. I'm unable to do the atziri fight as the key to the room is placed in a position where its impossible to path to atziri's chamber.

I've ran about 20 temples after unlocking the Keyroom, I've never been able to achieve the path to atziri's. and the keyroom wont dissapear. I'm royally pissed.
