so I've been trying to get into mariculture, but at one point you really need to find rutile ore before you can progress. now normally rutile should spawn near limestone, but Mariculture's limestone has been disabled in Monster. now I know rutile ore still spawns through a configuration from the worldgen file from cofhcore, but my only question is... where does rutile spawn? I've yet to find it so I'm guessing it only spawns in certain biomes or y levels...
