As per the latest post by Bethesda Software on official Reddit, the Milepost Zero update will go live as scheduled, but the Caravan feature will be available later in the month. https://www.notebookcheck.net/Fallout-76-Milepost-Zero-to-release-without-the-main-feature.883329.0.html
Lmao, have to uninstall to update the game, oops what if I just uninstall and don't play again, oops. Keystone feature not even launching, get a grip.
You don't need to uninstall. Start the game and you should then get a notification saying the game needs an update. I am on series X but I am confident that it's the same for all platforms.
I know, why are people being so confused over the update? Just say it's a very large update, not like thats anything new for FO76, the day one update when it first launched was basically a full reinstall as well. (so much for having bought it on disc so I could play it quicker)
You ***DO NOT*** need to reinstall the game on any platform, just update as usual. The update size is huge because it replaces most of the game's files.
