So i had the same bug, couldnt blow up the third tower. I did what you guys said. Cleared the whole instance before starting the escort. I succesfully took down the third tower. Then the quest tells me to talk to Tonn but i cant. I can only greet him. Already retried 4 times and the same thing happened. I cant talk to Tonn after i take down all the towers
