If someone helps me with my buildings while I'm killing zombies, just 1 minute after completing the stage (streets, residence warehouse...) I get this message: "Game couldn't be saved". Then the game refreshes and riuns whatever I've done, counting last stage as failed and making me wait 22h until I can do it again. It happened 3 times in a row, so now I have 3 objectives blocked 22h....
To all of those who are complaining about this game: believe me, you don't really need a lot of money to play it. I admit, at the beginning your energy bar looks pretty small and takes a lot of time to top-up. But after reaching certain level (adding up tournaments option) you can play this game for hours every day
