`http://site/some-slug` gets redirected to [http://site/some-slug/ID](http://site/some-slug/ID). That’s awesome.
But, `http://site/21st-some-slug` gets redirected to `http://site/whatever-slug-it-is-for-id/21`.
Is there a way to fix this? I’m poking around in `routes.rb`, thinking I could find a regex to change, but that doesn’t’ seem like the way.

Interesting, any ideas here @eviltrout? Probably a Rails routing thing.

That was trickier than I expected it to be, since it only fails when the topic whose id matches the same number exists. Here’s a fix:
