Material disappears from Recycle output slot

[Bastrabun]

Repro:

• Empty circular saw
• Add 99 cobble to the "input material" of the saw, take a lot of microblocks out
• Add more cobble to the "input material", so that its back to 99
• Add the microblocks to the Recycle output
• Take out the 99 cobble from the input material -> Saw resets to nothing, recycle input material is lost.
