There’s no guarantees in neither love or software I’m afraid @vikiv ??
But seriously, I would strongly suggest to always test any update of any plugin or theme on non-production sites before using them for the real thing. This certainly is not the first time a plugin- or theme-update caused issues and it will not be the last either.
Regarding solving broken-plugin issues; you can avoid having to do a restore by renaming an offending plugin’s folder-name (via FTP of from the command line) as that will deactivate the culprit immediately.
hope you have a nice day in spite of this unfortunate hiccup!
