Is there any way to fix the issue with having to re download the entire game every update...

Unfortunately the system is currently set up to delete the entire game if an update is cancelled. The only way to avoid that is to have the update download with any interruptions. I'm not sure why it's that way or if/when it will be fixed.

Thats fair, its annoying because it seems like only my xbox, when these big updates happen, instead of just downloading the update, re downloads every file. For examole the latest Balder gate patch should only be 20gb max, im downloading the whole 138 gb again. I understand some patches being big but xbox is the only one that doesnt just download a patch but the entire game.

It happens every time a game updates.

I started downloading this patch at 130 pm. Its now 925 pm and only progressed 98 gb. So likely wont be playing BG3 this weekend at all.

I cant play any popular multiplayer game like fortnite, cod etc because every "update" is really just downloading the entire game again. Id be happy to download 20 gb but not 100 or 200gb plus in cods case.

Is there a way to stop xbox downloading a whole game to update because that does seem exlusive to xbox.

Sorry if it my issue doesnt come across clear im not that good with words.

This answer does not address or clarify the reasoning of having to re download the entire game for a small update. I am having the same problem and am having to download the entire game for an update that stated it was less than 1gb.

if the update encounters an error or is cancelled or some other issue it cannot re verify the files and will download the entire game again.

I'm having the EXACT same problem with all my games that require a update. Destiny 2 updates just about every other week and it will tell me I need a 48mb update but it downloads the ENTIRE 36GB game EVERY OTHER WEEK!

Just noticed that I needed an update for Halo 5 and at this moment it is downloading the ENTIRE 107GB Game. Earlier this evening Dishonored 2 needed an update (dont recall the update size) but it downloaded the ENTIRE 54GB game.

MICROSOFT, Whats UP with this???? How do we correct this. None of my XBL friends I've spoken to have this issue!!

SO FRUSTRATING!
