We've got an issue in our forum since updating to the latest version of NodeBB. We're sorting our updates from new to old. With that setting, it doesn't seem to update anymore which post was last read by a user. So if you open a topic, it keeps on jumping to the same, old post - even though you've already read the latest one.
It works fine if I chance the sorting of posts to 'old to new'. Can anyone confirm that as a general bug? I'll report it on GitHub in that case.
