What broke in your production that no checklist warned you about?

Until this morning, the item count on this page was 20 behind the real list. It said 4,352. The list is at 4,372.

My own pre-push check makes every number in the repo and on the site match the data. Product Hunt isn't in the repo, so nothing was looking.

Fixed now. The check did its job everywhere it could see. The one place it couldn't was the page I'm launching from.

So, the day before it goes live here: what bit you in production that you never saw on any list?

If it isn't in the 4,372, that's the gap I most want to hear about.
