This happens to me constantly. It makes the game almost unplayable, yet I still play it. What does that say about this crazy game?

Please fix this bug as soon as possible.

This happens to me frequently. All of a sudden I will lose control of my character and I will be stuck running in one direction. No amount of button mashing, double clicking or cursing will stop it. I have to ctrl-alt-del then rejoin the game after the task manager comes up to stop it and regain control.
