If this issue only occurs in one browser, which browser is a problem?

No response

Describe the Bug

1. Start dev server (astro dev)
2. Change slug of an article
3. See that both the old and the new slug work and are shown in getCollection powered lists
4. Optional: Change the slug again and see more duplicates appearing
5. Restart the dev server
6. See that only the new slug exists

Happens in the most basic Blog example as well.

What's the expected result?

After changing the slug, the old one should instantly not be available any more (just like it is after a restart of the dev server).

Hi. I can't reproduce this in the currrent version. As you didn't share your own reproduction I can't tell if this has been fixed or not. Can you see if it's still happening, and if so then please share a repro.

@ascorbic I didn't create another reproduction since the original example repository (which I linked) already shows this behaviour. Here's a screencast. Please note the duplicate blog article at the end of it.

OK the part that was unclear was that you were referring to changing the slug in frontmatter, because the entries in the example don't have them. I was changing it with the filename, which was why I couldn't reproduce it.

No worries, I‘m glad the screencast cleared it up. Thanks‘s for the prompt resolution / PR!
