Okays guys I found out why the download seems buggy and you're tempting to pause and resume the download. So I looked in my windows app that contained the game it had two folders version 9.1.0.2 and version 9.2.0.2. What windows stores does is it downloads the update first, then copy's all the 70GB+ game from the 9.1.0.2 to 9.2.0.2. I found this out because I kept refreshing 9.2.0.2 folder and I saw that the file size was increasing everytime I refreshed as fast as I can. After it has copied all the files from 9.1.0.2 to 9.2.0.2, it will automatically delete the older version and you'll only see the new version. And you'll see in the windows store that it says play. So, when we all are waiting to play the game, but the update feel like its taking ages, its because it's copying all that 70GB+.
