"You still have 1 more message. These are the latest 25"
Okay... I'm stumped. How do I get to the "1 more message" that's waiting for me? I've tried leaving the area, coming back (the mailbox isn't doing its happy bouncy-dance thing). deleting a message (the first time I received this it read "26"). Help?
The messages it's referring to are ones you've already read; they're at the bottom of your inbox and have been bumped off the mail screen so you don't have access to them.
