@LeNitrous That's why people should save up oil, coins, cubes, and quick finishers. Buy cubes with merit or coins. Never buy them with gems! I had over 180 cubes, and when I heard there was a rate up in special construction for Tirpitz, Graf Zeppelin, Admiral Hipper, and Deutschland, I blew 60 cubes, 90,000 coins, and 30 quick finishers. Worth every damn resource, cuz I got all of them.
