Discourse Confused About the Number of Posts in a Topic?

[khenmu (John Sweeney)]

Hi everyone,

Can anyone explain what I’m looking at here?

I just saw this now here on Meta. I was browsing, while logged in, on my iPad. The ‘Latest’ home page appears to be insinuating that a topic with one reply has 313 replies I haven’t yet read, which… seems unlikely. Is this potentially due to the topic auto-deleting posts after a month?

I initially assumed that it was a display bug caused by posts having been moved out of the topic - but if that has happened, I can’t find any sign of it. I haven’t noticed anything else out of the ordinary.

This is the topic in question.

Hello, yeah this is a known issue. Here is the related topic.

Number of unread replies is different than number of topic replies due to reply deletions

We have had this reported a few times before, it is fiendishly hard to fix. If a large number of posts are deleted then unread count is artificially incredibly high. We could I guess do a client fix that caps numbers but it just replaces imperfect with more imperfect. Problem with counting deleted replies is that there is no cheap way of do it. You may have read 17 of the 32 deleted replies.

Ah, my bad - wasn’t able to find anything relevant.

Guess that’s what I get for using Google to search against site:meta.discourse.org.

Thanks for letting me know!
