Error 4894

I go to King.com.  Then I scroll down to bottom of the page and hit "contact us".  I then follow the prompts and tell them the problem.  That's how I do it.  They can see your account somehow from their end of things and they know what you did and did not do.  So they know what is going on and are usually fair about making things right when the error was on their part.
 

I went to the contact us page too.

Thank you for fixing.  It might be in everyone's best interest if you test these levels before releasing them to avoid problems like this in the future.  

They should sort out problems like this before releasing these new levels, rather than releasing them with errors.
