When I click on 'A HN post with negative points – how?' from the HN homepage (currently ranked 12 for me), it goes to https://news.ycombinator.com/item?id=48104663 instead of https://news.ycombinator.com/item?id=48106316 (I found the latter via google search for the title string)

I suspect the same is happening for some others too, based on the comments on that article.

Bizarre!

Update: 2 minutes later and the link from the hn home page now correctly leads to: https://news.ycombinator.com/item?id=48106316

Never seen that happen before.
