Freelook lock seems broken on PC
We can not lock Freelook on PC if you are a helicopter pilot that flies with mouse you would not able to fly anymore until hotfix.
Where you also see this issue is by climbing wall / climbing on ladders you can not turn your head.
Try to fly with mouse / climbing walls / ladders your head will be weirdly locked and stutter back to center.
If you press alt it will still recenter but wont lock at all. Hopefully we find a workaround for now or quick hotfix.
Also the head is locked while digging / dying (Uncon) / animation it was normally in freelook but by tapping alt it will go back to freelook again. Something seems reversed since the update.

Mainly helicopter pilots who fly with mouse and use the Freelook Lock feel the impact of this issue.
But also other animations where your normally would be free looking are now locked. Like climbing / mantling / using ladder / F1 animations / unconscious.
Hope this is enough info now to find the problem / bug.
Good luck team awesome game i love it ;) Bugs happen part of live development ^^
