Haedrig/Blacksmith missing forge animation

I noticed that whey I bring Leoric's crown back to Haedrig the smith, sometimes the forge is not in the world when he drops the crown, and then proceeds to repair it.

When I first played through the game on a wizard, the forge was there, with the crown on it, while Headrig hammered away.

The following two playthroughs (witch doctor, then barbarian) did not have the forge in the animation. The crown simply floated above the ground while Haedrig hammered it.

I can confirm this, it occurs on every playthrough with a new character for me.
