When starting a new Wizard Quest, after buying the items and hitting the button to turn the items in, this error spits out: "Fatal error: Call to a member function add() on a non-object in /www/subeta.net/include/mvc/models/quest.php on line 256"

It uses the items that I'd purchased for the quest, but does not finish the quest and no rewards are given. D: Just happened three times in a row. ;(
