DK Quest "The Scarlet Apocalypse" Bugged

As the title says, the quest is bugged. The DK must interact with the Lich King which is supposed to be over a stand (or something). Instead, he is below the texture, in range to interact with, but still impossible to interact with. When interacted with the Lich King, the character does the interaction animation, but no dialogue pops up. This prevents DK's from advancing in their questline and gaining talent points.
