Hello again. As promised, I recorded a video. I apologize for the quality (I chose not good recording parameters), but the essence of the problem is visible (and audible) well.
As you can see in two places in the phrases Cayde-6 no voice.
Also, I forgot to mention - the problem appeared after the release of Warmind. The problem is present for all my friends, and checking the game files does not help. For some reason, all my friends claimed that Bungie was aware of the problem and you just do not want to solve it.
Hello. I am terribly sorry, but I have already completed the mission with all my characters, and I would not like to remove one of my characters to re-run the mission. Unfortunately, I also failed to find among my friends those who did not complete this mission to join the battle group. As soon as I see this mission in the list of heroic missions, I will try to record a video.
