I need help with the item bar at the bottom of the screen where you put your skills. I accidentally duplicated it and can't find anyway to get rid of it. Then in trying to get rid of it I duplicated it again and now I got Item bars all over my screen. It sucks! If anyone knows how to get rid to these things please let me know.
