After searching on the net i decided to disband the quest then disable all addons and take the quest in nazjatar again by talking to bronzbeard again.
Take the portal to zuldazar  then from there to silitus and instead of ending up in the  room with the translocator i ends up in the middle of silithus with some  crystals and a enemy camp .

Either i am getting mad and see things or something is really miss with that quest

anybody else can give me some info if that’s the normal  start of that quest ?
