Made a post about mosin firing into the ground with no clear obstacle in the way, try messing with your fov options to avoid this issue before its fixed.

steep hills have this issue go to a hill and try to shoot down if your fov is messed up it will hit the ground instead of where you are aiming.

The same happens with m4 if you have messed with the Fov settings lower your Fov to fix this issue untill they make some changes to the Fov

After being shot or hurt badly enough character starts to moan/grunt using painkillers/bandages/eating and drinking to the maxium/using vitamins and antidotes moaning doesn't go away. restarting the client stops the moaning.
