Issue: Auto Project Table does not consume item before it starts processing it. Item is consumed after the recipe is finished.

Reproduce example:

1. Put Auto Project Table, below it put Hopper and connect the hopper to the chest.
2. Put Gold Ingot in the crafting grid to say 1 Ingot => 9 Nuggets
3. Put another Gold Ingot in the storage space below the grid.
4. Wait 1-2 seconds and take the Gold Ingot out
5. Inside chest there is couple of Gold Nuggets, but your Gold Ingot was not consumed at all.
6. This can be done indefinitely to produce unlimited amounts of Gold Nuggets

It works with any recipe with output of more than 1 item. Always when 1st item is produced you can pull out ingredient to "reset" the crafting process.

Fix: make the input items disappear when it starts crafting, not after its done?

In fact, the Hopper shouldn't be able to extract any nugget at all. I thought I blocked anything extracting less than the recipe output size. I'll have to add an internal buffer or something to indeed do what you describe.
