Crafting bug when switching blockheads in single player

In my single player world the first tap after switching to a blockhead that is crafting causes the action to be canceled. This happens everywhere except in the crafting menu itself, in which tapping is fine until you tap out of it, in which case the same happens again. This is all blockheads doing anything. It happens as if I tapped the abort button, and I receive all my items back. Has anyone else had this bug? Am I the only one?
