Idk if it's just me or not, but it seems to be having trouble updating. After a new post is made or replied to, it doesn't show up under my "new replies" or the " unread posts" I only find out they have been made or replied to by having to refresh and check each category on its own.
That's why I don't particularly like using those links to browse my posts... they're not very accurate.
It's always been that way. It's the software.
