It seems when users start up their launchers on the live client you will be greeted with a nice message that says -- Data for the next patch is available.
What does this mean everyone? It means we have finally begun the pre-loading of the 4.0.1 patch. Usually spread out over weeks prior to the release of a major content patch users can grab a huge chunk of the already completed items in the patch so not everything is downloaded on patch day.
To get the background downloader started all you should have to do is boot up the Launcher and make sure you have the options enabled to download in the background.
Enjoy everyone.:wave:
