UI reset?

[Bollwerk]

I just had this happen to me recently.
All of a sudden, like a week ago, all my settings reset on 3 of my 5 toons.
It was like they had never logged in before.
I had to redo all addon settings, keybinds and ui settings.
Basically everything except macros, which are stored on the server.
Extremely annoying.
It never occurred to me to backup my WTF folder, but I guess I should now.

I wish there was an option to do this on purpose.

I have so many toons across so many accounts, all with their own keybindings and macros and whatnot. Sometimes I just feel I should start over and setup everything again.
