(1)Toggle the camera mode with the home button and cycle back through to 3rd person fixed.
(2) Turn from a standing postition while you have the camera turned differently from where your character is facing using the right mouse button.
Result: The camera instantly moves to the direction your character is facing instead of having the character move in the direction your camera is facing (which is the correct behavior before toggling camera mode changes it).
This bug was found while I was terraforming and scavenging with a lot of stop/go movement and turning. I messed with the camera modes and this bug popped up.
