Since I've been playing the Witcher's DLCs I am frequently bumping into the issue where I am 'locked on' to an enemy, shown by the orange border on the level of the enemy. (But I'm not entirely sure it only occurs in the DLCs.) I think I do this by pressing a key combination by accident. What happens, then, is that Geralt starts moving around by himself. He also casts Axii without me telling him to.
I haven't found how to turn this off. Reloading a save game does not stop it, but restarting the entire game does. What is this and how can I turn it off? What is the key combination for it?
