First off, it is highly recommended to restart your device often. If exiting the app and restarting your device don't solve the issue, I think it might be a bug. Unfortunately, there were many others in the past and perhaps there will be more in the future.

Other bugs and others technical issues have been reported [|here]. You can check this site from time to time when things don't go as they should and see if someone from King answered.
