For some reason, whenever a new update comes out for Destiny 2, all of my friends only need to install the 2 or 3 Gb for the update, yet I always end up having to download a massive update in excess of 80Gb. Why do I have to seemingly download the whole game while everyone I talk to only has to install the new stuff? I'm on Xbox and in the UK, but I've talked to players on PlayStation and in the US and haven't come across any other people with the same issue. I just want to know why this is the case and if there is anything that can be done about it so that my clan doesn't have to wait a whole day for me to install a simple update.
