话题底部显示“还有1个未读”实际上没有未读话题

[JammyDodger]

我也之前报告过这个问题，但有人指向了这篇帖子：

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.
