Whenever I aim down sights and turn my view, the viewmodel will sway, but it never centers again. For this reason, ironsights are nonfunctional to me, and I can't find what's causing it. Can somebody help?

If you can see it (because my crosshair is thin and black), the gun will not re-center on my crosshair after I turn.
EDIT: the viewmodel re-centers when I fire the gun, which is still ♥♥♥♥♥♥♥♥ for weapons like the M1014 and most that have large lens sights.
