Hello @csuper Hearty Welcome to the Candy Friends section of our friendly King Community
I am very sorry to hear about the issue in your game!! Did you try the "Troubleshooting Steps" that was provided in the link given by my friend @Mattia_
** With regards to your question that if is an affect of the Update!! It should not be... because, I have updated my game number of times in the past year and have never seen this! But, I will find out from our Friends' Community Team
Please post back how it went with the trouble-shooting steps, and if you need further assistance, please post back by tapping on "Type your Comment" box located below.
