For example, making straw hats cannot be cancelled by movement, it will just restart crafting - this is not breakable by switching crafted item, moving, or even closing the craft window.
Using objects with an animation and then breaking the craft by movement once, will continue a new craft and finish it no matter how far away. If broken the animation will remain, for all eternity.

This is a very serious bug, it's gamebreaking, a proper reward should be in place for this. *fish fish*. And I'm aware it was said the crafting was uninterruptable, however...
