I was looking at the alchemy tab and found a few inconsistencies with items and recipe names- namely the grinding ores into powders. Iron ore processed WITHOUT the macerator turns into lead powder. Also, 2 of the recipes for making phosphorous powder make lithium powder instead (the macerator and the mortar-and-pestle/grindstone/laboratory recipes). I am using version 8.1 of the hydrocraft mod according to the change notes.
On a side note, there really should be a dedicated bug report section. Preferably pinned for easy finding. Keep up the great work.
