Check your storage space. I would think that it could be an issue of your hard drive just not knowing how to handle a sudden 'swap' of data (My game is at 34.4GB and I've been on Xbox One since July). If your hard drive has at least 50GB then I wouldn't bother messing with anything on there. If your console is wireless, attempt to download it with an ethernet cable plugged in. It could just be a random timeout thing going on. Post back what/if this helps. Thanks!
