Hello, I run the 5.4 launcher in a WoW folder that was updated to 6.0. Every time I play, my game is continuously downloading. If I allready had the latest version, what is it downloading? And is there a way to download it all at once? Because in the week I am not at home and I don't have acces to a very good internet connection so it is a bit annoying. Greeting, Mogue
