Anyone else has a problem with this quest?? I have to focus the light beams using frost and fire spells, but nothing works. First i hit the crystal with fire they move, i try fire again nothing hapens. Then I hit it with ice they just move back to the previous position. I hit it with ice again, nothing hapens. I can't seem to get the beams to move to more than 1 position, is this a glitch or what???
