I’m trying to get my Hunter caught up in the Lightfall campaign and when I go to do the Desperate Measures mission I find that it stops loading properly when I get to the Anti-Air Cannons that are supposed to be destroyed after beating a yellow bar enemy which never spawns. I have restarted the mission a few times, same issue. All the initial red bar enemies are at each cannon, but nothing else spawns after they are defeated and no mission dialogue is played.
