Inbox shows unread messages

My inbox shows that I have two unread messages but I do not have any. Even after deleting the majority of my inbox messages it still shows up.

Same, except it seems to be counting all messages in my inbox. The number 172 doesn't change, even when I mark everything as read or delete PMs. Also I don't get PMs anymore when people @ reply me, even though I've that setting enabled.

Yup, same here. Inbox icon shows 10 unread messages that I can't get rid of.

There are multiple bug reports on this, please check before you post.
