I don't know what "bugged" means but what you're seeing is probably an artifact of HN's re-upping system. We re-upped this thread and that relativized the timestamps on the previously existing comments (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...). Sorry for the confusion—I know it's weird but so far no one has come up with an alternative that is less confusing.

The reason I re-upped this post, btw, is that it was at the top of a list called "underwater" that we try to look at every day, which lists the most-upvoted posts that for whatever reason didn't happen to make the frontpage. This was at the top of that list.

Sometimes similar articles are merged into one. Including the comments.
