One of the quests in the book has you upgrade 3 iron mines to level 3. I had 2 mines at less than 100, so I turned them off to upgrade. The (resources) upgrade button darkened to show I can't do it again... but the upgrade never happened. I tried turning the mines back on, no luck, and the button stays darkened.
Also, when searching out copper, my geos are twice as fast as the regular server, but not for any other search?? Is that supposed to be right?
