Not exactly a bug but the recipes for ingots such as soul steel, enderium, shellite, twinite, and dragonsteel all provide more ingots if you instead craft the dust and then smelt. Some provide double the ingots like dragonsteel, some only provide slightly more like Shellite, and Enderium is special in that it only doubles if you use platinum dust and an Ore Hammer. This feels a little out of place as it seems as though you should get more from the induction smelter recipe rather than crafting dust, but I wanted to report it in case this issue was not made aware before.
