I have the same issue / question about base upgrades, as well as more levels?! I have been on Level 40 for weeks and really can't do anything but mostly "lose" diamonds to battles when I am not logged into the game or take diamonds back by "Revenge" battles, which gets pretty boring. In addition, I am on "Europe" Campaign…
Missing gold as well. I have followed several links to "Get More Free Gold" and actually purchased 2 items, which should have credited me over 800 gold, but did not receive! Any suggestions?
