yeah, stop using custom interfaces. You will need to redownload/reinstall.
Yeah just about that in short. Basically the files coming out from updates or verifying the files finds the files being shared to
everyone. Not everyone's gonna have the UI you have.
I personally lose my custom UI only when verifying the files or after a much bigger patch, but otherwise I've managed to keep mine. Just keep backups of your interface and surface and copy them in again.
