0.1.5.1 Server: Hopper on top of hammer mill isn't working

[valsnoisytoys]

When you put a hopper on top of a hammer mill (or on the sides for that matter) the blocks just sit in the hopper and don't get pulled into the hammer mill. Table sieves work fine.

Works fine for me. Try putting a chest under the hammer mill if you haven't already.
