Not sure how this should be changed in discourse, but those 2 numbers are very different and 155 is misleading since all the replies were deleted. Would it make sense to not show the “number of deleted replies” when counting the “number of unread replies” ?
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.
Viele Beiträge werden hier automatisch durch die allgemeine Forenwartung gelöscht (z. B. „Alle Antworten auf dieses Thema werden nach x Zeit gelöscht“), da Meta seit Beginn von Discourse existiert.
Und das ergibt auch Sinn, es ist nur verwirrend zu sehen, dass ein Thema angeblich über 600 ungelesene Antworten hat, nur um das Thema zu überprüfen und eine zu sehen.
