When I am on a hill, lying down prone with my Mosin near Elektro, my bullets will show to have hit the dirt sometimes, and I am rendered incapable of hitting the target I am aiming at. This is resolved by going into the crouch position or relocating myself.
Notice, this problem is only on some hills, but there is nothing actually blocking my bullet nor my aim. It appears as if the bullet acts like the melee system - so the bullet hits where the gun appears to be aiming, and not where the cursor is.
