I use this config:

[ { "baseRegistryName": "minecraft:gold_ore", "depth": 5, "hardnessMultiplier": 9.0, "recipeEnabled": false }, { "baseRegistryName": "minecraft:iron_ore", "depth": 5, "hardnessMultiplier": 9.0, "recipeEnabled": false }, { "baseRegistryName": "create:copper_ore", "depth": 5, "hardnessMultiplier": 9.0, "recipeEnabled": false }, { "baseRegistryName": "create:zinc_ore", "depth": 5, "hardnessMultiplier": 9.0, "recipeEnabled": false }, { "baseRegistryName": "iceandfire:silver_ore", "depth": 5, "hardnessMultiplier": 9.0, "recipeEnabled": false }, { "baseRegistryName": "tmechworks:aluminum_ore", "depth": 5, "hardnessMultiplier": 9.0, "recipeEnabled": false } ]

Before i added the aluminum line everything worked fine. Now after i added it, it only loads gold, iron and aluminum.

I am using version 1.0.16

Update to at least version 19 there where changes in forge that are dealt with in later version
