I could dump an endless amount of videos about this issue. How much time before/after do you need? How many clips do you want? 10? 20? More? I can probably get 5-10 perfect examples per match.
This is incredibly frustrating. Of note with that clip is the 2x trappers and flamer were also silent. Audio indicated 1 hound and 1 mutant. That is very different threat level than 1 hound, 1 mutant, 2 trappers, 1 flamer.
