Hey there, sorry for any alarm/potential disappointment. During an update to the Launcher, an old build was incorrectly committed to the Public Beta branch which would result in you downloading a bunch of data. (To clarify; there is not a new version of the game out on the Public Beta.)
The version error has been reversed on our end, but anyone who already downloaded the “update” will have to re-download, as what you did download won’t actually function.
That said, we do have an update headed to the Live game soon. Keep an eye out.
