The Iron Bull problem. (Dragon Age: Inquisition)

Took a quest to visit the bull commander from Kram. Teleport to the storm coast. I see a wheelhouse nearby and there is a quest marker. Helping to kill the venatori bulls. I killed the latter and nothing happens automatically. The cut-scene did not start. I cannot talk by pressing the action. And when I come up to these bulls, they turn around, retreat a couple of meters and again defiantly turn around. What the hell is this bug. Who knows help. Thanks in advance.
