I was playing Dayz and I noticed that in update 1.26 you fixed the head movement so that it didn't rotate 360º when performing some actions.
I accidentally pressed the ALT key while performing an action (I later tested with several) and I noticed that even with the block, my character still turned his head 360º. All you had to do was rotate normally up to the limit while performing the action, and clicking the ALT key continued the rotation.
