All of a sudden when I start talking to npcs no captions happen and I can't move and when I relog the same thing happens again. There isn't much to do because I can't continue the storyline without talking to them any help would be great. Also, I can still see all the npcs moving and see other players moving around as well, but I am like frozen. When I relog I am able to move, not quite sure what could have caused this.
