Do some tail'ing on your logs and see if you're being redirected to multiple actions before you render. If you are, it's likely that flash isn't being kept long enough to make it to the view where it is finally rendered.

A well-placed flash.keep(:notice) should do the trick.

Much later edit: Also, in retrospect, if you're redirecting that many times, I highly suggest you do some refactoring and eliminate any unnecessary jumps by consolidating your redirect logic at a higher level, so that your redirects are predetermined and only happen once, twice max.
