I am playing my own modded Minecraft with several mods and was happy to see how Aluminum ore could be processed through Railcraft and Gregtech without having the smelting recipe from ore to ingot. This made making Aluminum ingots or 'Aluminium' products from GregTech hard because in my modpack this meant you needed more advanced GregTech machines to be able to process it. I was using the default download for Galacticraft (build 1010) back then. We noticed that this version (1010) was causing lag issues and other problems and I decided to update to a latest development build from Jenkins (1044). Ever since that update, Aluminum ore is no longer recognized by other mods, making it impossible to process it with those mods (apart from smelting in any type of furnace) and allowing normal smelting to ingots again. This changes the level of gameplay, because now I can smelt to ingots in any furnace and then use the resulting Ingots to do further processing with the mods again if needed. Example: Previously I could only process the ores to get to 'Aluminium' dusts and to 'Aluminium' ingots through GregTech/Railcraft ((Industrial) Grinder/Rock Crusher (dusts) -> Industrial Blastfurnace (Ingots)). My modpack is supposed to be hard-mode and I loved the fact it needed mid-tier machines to actually be able to get to the 'Aluminium' ingots. Now the balance is broken for my modpack. Did Ore Dictionary Registry for Aluminum change to break compatibility with the 'Aluminium' used in other mods? Is there a newer development build on Jenkins available that fixes this issue again? Do I have to start a fresh world and disable Aluminum ore to spawn by Galacticraft to fix this?
