Demands of the Qun: half the conversation is missing
After I light the signal fire at the end of Demands of the Qun, the quest becomes seriously bugged: I hear my comments and Iron Bull's, but not the person we're talking to. I presume it's Gatt, but he vanishes from the scene, and I get several shots of vague grey rain; I'm not sure whether that's the background where he ought to be standing, or whether other things are missing, too -- entirely possible, since the grass tends to flicker in and out when the camera shifts to show my Inquisitor and Iron Bull.
Running on a PC; let me know if you need other system stats. If there's a way to resolve the bug, let me know (I tried re-running the quest, with no success). I'm able to finish it out, but it loses a lot of its impact with half the conversation missing, and right now I can't do any of the things I want to at the Storm Coast, because I can't go there without it triggering this quest.
