becouse its to much of work and cannot be done easy in xml as far as i know , it also break balance of game( 50 in each x 20$ = 1000$ each , times 25-45 in vein ... ) so mod is good but idea not so great is ther any other use for them then sell ( and 50x25 veins for diamond do you know how it is in real life 1 carat every 5 ton )
Hi,instead of to add vein's as diamond source, why not a low chance to find diamonds when you regular mine, like stone chunk's.And when you craft chunk's into block's there could be another chance to craft diamond's instead blocks.
