Map Transfer Error Occurring at Login

I was just about to hit play selecting one of my characters and start playing but when I hit play a message stating that there was a map transfer error giving me the option for either normal or safe login appeared even though it was my first login of the day and I had not even been in the game yet. It is possible that this could have been caused by a background error that occurred that I could not see in the back end. But just in case it is a bug I thought I would pass it along. Thank you for making such a great game.
