Don´t know where to go with that issue becouse there are 3 Mods Involved so i start here.

Issue description: External StorageBus attached to a Quantumstorage (Item)+to the Ref.Stor.System
Put (Mekanism) Osmium Ore Into the Quantum Storage.
Set The Filter of the Bus for Osmium Ore.
I was testing a bit and if i put the Ore into another Storage like DiamondChest, the System CAN see the Ore.

What happens: The Ref.Stor.System can´t see the Ore

What you expected to happen: the Opposit of corse ^^

Steps to reproduce:

1. Fill QuantumStor. with some (Mekanism) OsmiumOre
2. Atach a Ext.StorageBus to the QuantumStor.
3. Set the Filter For OsmiumOre
4. Take a look in the Ref.System
