Well, I for one will no longer buy gems to buy deposits for my mines. That was useful for avoiding using large amounts of resources to build new mines. However, since I was not allowed to login for 10 hours (12am to 10am CST) due to a glitch in their system, I had 2 coal, 2 iron, and a gold mine exhaust. From now on IT'S A FREE GAME, EVEN IF IT TAKES LONGER TO ACCOMPLISH THE SAME THING.
