Issue Description:

So this is my little setup to make Blank and reinforced slates. In the filter I have 1 blank stone output to the North side (blood altar) and one output of four blank slates and three reinforced slates to the South side (Chest)

What happens:

The altar takes stone and makes blank slates that are taken by the chest twice, then the altar keeps the stones until they become reinforced slates three times and deposits those in the chest. The altar then takes one of the remaining two stone and leaves it in the altar

What you expected to happen:

The altar should take one stone and deposit it back into the chest when it becomes a blank slate four times rather than only twice and then create reinforced slates.

Steps to reproduce:

1. Create above setup
2. apply two filters to the output node, one to the altar side with one stone ghost item, and another to the chest side with four blank slate and three reinforced slate ghost items
3. Link nodes
4. Place seven stone in chest
5. Watch the magic
