for the dev version: whenever a silent rotation is being made 4 values are printed, the first two target and current are the inputs for AimSimulator.rotMove, whenever current is above 360 the rotationhandler breaks and you vibrate around
Try the "normalized" smoothback mode to see if it gets fixed (it does)
the non dev version replaces the "default" mode with the fixed one
though still whenever the bug would have happened you can see that the direction of rotation to the view angle unexpectedly changes
