Adds a another impurity to coal vein (iron) and another impurity to stone vein (copper). Coal vein no longer overlaps iron vein. Iron and Copper veins slightly narrower than before. Made weights for each cluster add up to 100 so percentage becomes obvious.
Added in a small amount of scattered ore since it may take players a little time to find each of the four primary ore types. Slight reduction in copper and iron ore.
Instead of the heavily mixed ore pattern used with Diggy in the past, this ore pattern contains ore tendrils that are about 80% pure ore with lower impurities. Feedback encouraged.
