So, despite the patch notes mentioning that this one was fixed, I ran into another bug with this story step.
After Tonn bombs the third tower, I cleared the beach of undead. After that, I got the checkmark saying that I’ve completed that step…but nothing afterwards, no indication of what I need to do next.
Thanks for the info! While this was previously fixed, it sounds like it’s broken again, so we’ll take a look.
Do you remember what you did prior to the quest getting stuck? We haven’t been able to repro this issue, so any additional details would be appreciated. Thanks! 
I managed to get this done by inviting a pal and she went ahead of me killing the mobs while I stayed with the caravan.
Though I quickly caught up.
Seems the two of us together managed to kill fast enough before the towers were blown up early or something.On this 2nd run the two escorts also didn´t get stuck, so that may be a factor.
P.S. with “getting stuck” I rather mean just stopped moving. There was nothing whatsoever that hindered them.
Also in my 1st post I angrily forgot to add, that at some point before that 3rd tower blast for a while the Asura-demo-guy somehow found a levitation spell or something.
As we came down the hill to the 3rd tower.These new problems might been connected to that fresh bug?
Thanks for the additional details! We think we may be getting closer to identifying the issue. If you and your party member stick with the caravan, does that allow you to progress?
