I'm currently on Arkadia but I have a S.I. Hk110 I noticed since the VU the gun has an added sound. But also when others in the distance are shooting I hear that same extra sound as if I was shooting making the sound. When I get near to the person shooting I hear the normal sound of their gun. I don't know if it has anything to do with it but I hear trees blowing in the wind on my ambient sound now. (Celeste Quarry)
