During replays, background sound at ground level on BoK map is sound of waves...

...even when camera is on land

its not just during replays its also while you are flying on a mission.
its just hard to hear over plane engines and the wind.

but yes it will be fixed with next update im sure.

Strangely, I only heard this myself for the first time today when I was replaying a Track.    I decided it could not be waves and must be the wind but it does sound like the sea.
