So i got my first mosin yesterday with a long range scope, i was tyring for about an hour to make the scope steady when i zoom in. Made sure my character was healthy, checked keybind for hold breath and its "hold second mouse button" as default however when i zoom in it won't hold its breath. I've tried changing the keybind and still no luck? Attachments i have on the mosin is a compensator and a long range scope. tried proning no different? Any one know anything to help me?

Actually yeah, now i think about it, it keeps coming up in the bottom left saying "My leg is in pain" Never thought about it affecting it but im guessing it does? Its not a fracture or anything so, do i need morphine to make it better?
