Doctor Who 30 Years Convention
From Tardis Wiki, the free Doctor Who reference
In Earth-33⅓, at a Doctor Who 30 Years Convention, a group of fans discovered that the Dalek toys they all brought had been impacted by the mysterious demat effect, meaning that the "arms" (eyestalk and manipulator arm) of the Daleks had dematerialised out of existence. (COMIC: Doctor Who? 205)
