Fixed a bug where the dummy player head wasn't replaced with the crafter's head if the crafting result was sent directly to the crafter's offhand using the offhand keybind.
The crafting result will still look like the dummy head after sending it to your offhand, but this is just a visual bug. It will update as soon as the head is moved, the crafting window is closed, or the head is dropped.
Updated the version in the pack description to be 1.21(.1) instead of 1.21+, as 1.21.2 will have a higher pack format.
