You see the issue is that we have so many people mining. It is the new way to earn money quick. So we need more mines. There is 8 People mining Diamonds alone. We only have 12 rocks to mine. We need more rocks, why not add another room down stairs where the Gold Shap and Ruby are at. Make it two rooms emeralds after ruby and shap and dimaond the next.
We are miners and we need more rocks to mine in peace. or add more mines as you said you would along time ago.
Mining is the new best thing.
