Hello @atousign68, Hearty Welcome to the Candy Soda King Community

I am sorry to hear about the technical issue in your game and also for loosing your Gold Bars!!

Can you provide these below details --
1) What device are you using to play the game;
2) Are you logged in through Facebook or Kingdom account!  
3) Your game user ID number -- find it through this link  https://community.king.com/en/candy-crush-soda-saga/discussion/247075/what-is-my-user-id-and-where-can-i-find-it/p1?new=1

Once you write all that needed info, I will send the complaint to the Community Manager to look into the Gold Bars issue. 
And with regards to the "Error" issue, the King Studio is working hard to find the reason for the issue as well as a fix for it! 

Until then, we have to be patient and make sure from our end that the device is all good with enough storage space, etc., and the game App has the latest version!  

Talk to you soon!  Have a great weekend!
