I'm not sure if this will happen with any other game, because Halo 5 is the first Xbox One game I've owned.
So I got my copy yesterday and shortly after installing the game I had to install the day one patch. Figuring this would take a while, I went to do other things for a couple of hours. Five hours later the patch is at 85%. This morning when I woke up (Thirteen hours after the last time I checked) the patch was sitting at 94% completion, and now (eight hours later) it is still at 94%, and keeps queuing every three to five minutes. Can someone tell me what is going on?
