Added to the pile of reasons I'm loathing Microsoft more and more. It's a shame Asobo and a damn good sim are caught in their clutches.
They have a world-class delivery system, yet use a launcher that doesn't seem to justify its existence much given that it has to redownload a crapload of data all the time anyway. That would be fine if it didn't void the refund policy to the tune of American's data caps burning.
