Ah, is that I asked my friend to send me a mount, and when I go to where the mailbox is and I see the message and the mount is there but at that moment the game closes and when I go back to the I'm no longer on the same side and I realize I'm about 15 minutes behind. I had already done some quest and had to do it all over again, and when I go back to see the mail the saddle is gone.
