Does editing the title on old topics fix the problem?

If so, something like this might work on the rails console:

```plaintext
Topic.all.each do |topic|
    topic.title = topic.title
    topic.save!
end

```

(Assigning topic.title re-generates the slug)

Please please please take a backup before trying that, as I don’t know if it will have any unintended side effects.

It might also take a long time to run depending how many topics you have…
