I turned in the lightning-aspected crystals, however when I got the 'Quest Complete' text the quest did not complete.. now I am stuck on the same dialogue box, unable to progress.


P.S. I requested a name change in game because my name was offensive (didn't take it seriously when I first started) they managed to change my in-game name however I have been unable to edit my forum name.

Many Thanks
