We were at the end of the molten furnace fractal, right before the weapon tests. We entered the room as usual but at some point the dialoge of the weapon test engieneer stopped and the fractal didn’t proceed with the weapon test.
Wiping and partial reentering of the dungeon didn’t solve the problem so we had to quit that run.
I don’t realy know how this bug occured, i guess we were maybe too fast for the trigger, as Braham and Rox were starting their dialogue quite late in comparison to other runs.
This is a known bug and an older thread which I could not locate explained this is low on the devs list to fix. As you pointed out it can be rather easily avoided by making sure you wait for the npcs which can be slow at times. Fortunately this makes it less game breaking than the Cliffside bug which is much harder to avoid.
