I'm using TSON Craft and TechReborn, all latest versions as of this post and latest version of forge (2282).

TSON Craft Aluminium Ore is ground into TechReborn dust by for example Actually Additions crusher and can only be used in TechReborn Blast furnace while TSON Craft's can also be smelted by a regular furnace. They seem to bear the same OreDictionary entry of "oreAluminum" so maybe this is intentional?

Would be great if the dusts were equal.
