It happened to me 2 times now, that the character would get stuck into a position and could not move or use any skills. I could open a portal, but could not move into it. First time it got “unstuck” after about 10 seconds. Second time after 20-30 seconds i saved and exited.
The only commonality that i may have noticed is that when this happends i have really high apm, clicking really fast on the mouse/keyboard to do stuff. Not sure though.
