Just a heads up for you guys that are testing IC2 Experimental
If your Ore Washing Plant (OWP) that is next Thermal Centrifuge is full of Small Pile of Dust (any ore) and you have un Ejector Upgrade in the OWP to eject to the TC you will lose the Small pile of dust, because the machine does not recognize the inventory having a full stak of small pile of dusts.
