Shaft aiming problems back again. All shots going right and low. Not much of a sight..... When will this be fixed?

Not sure of this is what is causing the problem, but the sight on Shaft gun is no longer working properly. I aim as usual but all shots go low and to the right. Happened today. Only changes are promotion to Warrant Officer 2 and the mouse update. Tried on many battles and servers. Same result - all shots go low and to the right. Suggestions appreciated - as it is, shaft is not usable anymore for me.

Promoted to Warrant Officer 2 and the sight on Shaft gun not working properly. Aiming the shots normally, but everything goes low, right. Any ideas what is causing this and how to fix? Thanks
