Same issue, it started up just a few days ago! It seems like sometimes the game isn’t properly realizing the right-click is held when moving the mouse: IE, I can right-click and hold and move the mouse and the poitner just slides around. Sometimes it will spontaneously pick up the movement and begin turning, other times I’ll get no right-click-to-turn movement at all. Something is up and it’d be awesome to see this addressed. Be sure to bug report it!
