I broke the game before it even started. If you spend all of your money buying zombies, you can't buy an employee to attack a country. Going to the main menu and selecting new game doesn't help. You keep getting the popup to buy that employee. Refreshing the game appears to fix it, but you might want to put a hard limit in so that doesn't happen.
