Anvils are bugged

Basically anvils do not work at all right now (mainly the original anvil). You can't placed renamed items in item frames, a renamed item disappears once you open the anvil again, you can't take out the item you renamed from the anvil (unless you shift+click it)

Here is a video that shows more of what happens: https://www.youtube.com/watch?v=KDJ8iQML9Ig
