New Season 2 Update broke Tank zoom.

Since the update the aim sensitivity when zoomed in has been halved. The new settings have no effect on it. I can change the vehicle aim sensitivity for 3rd person and for zoomed in at the same time, but not individually, even though thats exactly what these new settings imply to do.

The remote controlled gun (MG Turret) and other vehicles like the Sliders gun are not affected. Only the MBT and IFV. I restarted the game and joined several different matches to test this, the new settings seem to have no effect.

Also the Settings "Vehicle Mouse Aim Sensitivity" seems to be broken. It appears twice, once in the "Mouse and Keyboard" settings tab, and once under the "Vehicle Settings -> Aim" Subsection. But the one in the subsection always has exactly half the value of the one in the "Keyboard and Mouse" menu - changing one changes the other exactly by a factor of 2. This also reflects the halfed zoomed in aiming sensitivity. 

The "Zoom Sensitivy Coefficient" does also absolutely nothing.

Either one of the settings is mislabed, or its writing a wrong setting internaly. Either way, after 30 minutes in the settings menu I cannot fix it and confirmed it to be a bug. I did try and change the vehicle individual settings, turned on and off the uniform aiming, everything.

Im on PC (Windows 10) using the Steam version.
