None of the anvil functions work. When I put in my two Power I bows, hoping to upgrade to a Power II bow, I couldn't get the Power II bow from the slot. Then I tried to merge two Sharpness II swords, hoping to get an Sharpness III sword, and named it Knife but that didn't work either. I checked my experience and certainly had enough experience points. I created a new creative world and it didn't ork there either please fix this bug. __
