Config files aquacavern-veins.cfg and caveworld-veins.cfg have sections defining Infitite ore generation, but it seems that ore is not generating at all. I checked aquacavern and caveworld worlds, using worldedit commands and I figured out that this ore is absent in random 100x(from bottom bedrock to top bedrock)x100 blocks in that dimensions.

All config files are default.
