The mod appears to only be looking for the vanilla chest and not other mod chests with the chest or chestWood ore dictionary tag. This is a problem when using mods like Charset Storage - Chests that add an actual Oak Chest, Birch Chest, Spruce Chest, etc. rather than using the vanilla chests which are not craftable. These chests all use the chest and chestWood tags. I suspect this may be a problem with other mods like Quark that add vanilla wood chests as well but haven't checked.
