Hi. I have a similar problem. I have deleted everything in the game and so can't do any challenges and can't do any invading because my Farm invasion % is to low. So I'm completely stuck and can literally do nothing. So it would be great if I could restart. I don't mind restarting, in fact I would like to restart it, but I don't know how. I have tried removing the app but it doesn't work. So please help me. Thank you.
