Is the world gen different for diamonds in this mod than from vanilla? Reason im asking is that I have now spent about 4 hours in the layers normally where they spawn (under layer 16) and have only found 3 diamonds. This is with me being in ravines and big caves with alot of open space but no luck at all. In vanilla I would find like 10+ within an hour doing same thing. Any help would be great. :-D
