Themes stop working once upgraded to SP18

[Ritz]

Hello Experts, 

We recently noticed themes associated with flavors stop working once we upgraded to SP18. I thought as themes were created in previous version and that could be the reason so opened the theme in edit and made small changes to get SP18 property adopted, but it didn't work. 

Please share if any faced this issue or if any fix is available. 

Thanks

It was due to flavor modification in higher version and moving to lower version. With service pack upgrade it got fix. Closing the thread. 

Thanks
