the black hole controller in industrial foregoing does not play well with refined storage if you use the extrnal storage from refined storage and set it to high priority whitelist cobblestone and then you put a black hole controller attached to it and insert a black hole unit that has lets say 100k diamonds then place some cobble in you system those diamonds will be converted to cobblestone this bug also works the other way and you can turn massive amounts of cobble into diamonds
