After updating my personal 1.12.2 pack's version of Ex Nihilo Creatio from 0.3.2 to 0.3.3 and loading my existing world, I received the standard forge warning for missing blocks stating that Ex Nihilo Creatio Aluminum Ore is no longer present. I have not tweaked any config settings or anything like that nor do I have any special instances of Aluminum ore set to spawn. I do use several mods that add their own Aluminum ore however. Has there been changes to aluminum ore that would explain it being missing after updating?

Changes were made to prevent the creation of both aluminum and aluminium. One of them should still be registered.

Ah okay, that makes sense then. I do see Aluminium is indeed registered. Thank you for the response.
