I'm not exactly sure. I updated the mod and core mod, making sure to pull my ingots and ores out of all containers and kept them in my inventory before I did so. After updating, I wasn't getting any ore-gen in my worlds... I checked the config, and noted all ore-gen was set to false. I updated the config, set everything to true, whitelisted my dimensions, and even deleted the mining dimension entirely, but I still wasn't getting anything. I ended up just using void ore mining (which was on my itinerary anyway) so I've got more than enough yellow goodness to go around.
