In mission 2, as soon as the refueling is done and I gain control, any further voice lines don't play. I can still see the subtitles on the top left, but no audio accompanies it. Happy to provide any further info, could be something weird on my end, not really sure.
SOLVED: During the cutscene the volume of COMM 1 was lowered to zero, which is the channel the comms were coming through. Not sure if that qualifies as a bug but hopefully this will help someone else.
