Hello, I have been playing Kingdom Rush for the past day or two with no problems. I invested in the premium content and played for a while with no problems. I exited and restarted the page but the game will not load. Everything appears normal except my profile information and a grey loading screen. I have looked into the issue and have read something about linking my account through Facebook. Is there an issue that is currently being examined? I would really like to resume playing the game, especially now that I have invested some money into the game. -Thanks for your time in advance.
