Engine Error: unpack iconic

I was doing nothing but observing my town when this occurred, though I did have crafter’s crafting things at the time.

Steps to reproduce:

  1. Play the game normally.
  2. Instruct Hearthlings to craft wood and stone objects.
  3. Wait to see if you get this engine error?

I apologize for a lack of screenshots or text copy. I seem to have left them both in my other jeans. (read: other gaming rig)
