The game used to be great, but a couple of days ago a problem appeared. For some reason, when I open friends list, it says to me that I don't have any friends (I'm logged in via Facebook) and I can't receive or send gifts at all, although I am constantly getting notifications that one of my friends has sent me a gift. It just says "Loading" to me. I tried to reinstall the game and log out of Facebook and log in again, but nothing helped.
