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.

If you press alt it will still recenter but wont lock at all. Hopefully we find a workaround for now or quick hotfix.
