The interaction between an Ars Nouveau Spell Turret and a Storage Drawer drawer allows for infinite duplication of any block. This includes duplicating a Better Crates crate with any item inside. When the turret is set to pull from a Storage Drawer, it does not use up an item when pulling and instead spawns a duplicate.

How to reproduce:

1. Place an Ars Nouveau Spell Turret, provide it with Source, and give it the spell Touch -> Place Block -> Break -> Extract.
2. Place a Storage Drawer next to the turret.
3. Add any block into the Storage Drawer.
4. Give the Spell Turret a redstone signal.

Relayed from FTBTeam/FTB-Modpack-Issues#971, thank you in advance!
P.S. Ars Nouveau v2.5.1 does not have a mention of this problem in its changelog, so I'm assuming it is still happening v2.5.1+

Fixed in latest version
