I tried to complete this mission 3 times so far. Once I found same problem as described in frist post but I also found another one.Tonn freezes at the second tower. Just stands there and do not want to move. He joins after you reach third tower but he will not blow it up. Edit:Well, I'm after another try. Killing the kraits last didn't work. I killed two kraits after "clear the beach" was active (third tower was already blown up).Also Tonn's freezing at second tower seems random or I lack the tools to find any connections between player's actions. Looks like it doesn't matter if you kill all the monsters there or leave one or two alive.
