If you've watched all of Amazon's Fallout TV show by now, odds are you're either on the verge of - or already have - hopped back into one of the games in the series. You're certainly not alone in the regard, but if you've picked Fallout 4 on Xbox specifically, you might have run into the small problem of achievements just not unlocking.
Yup, while it arguably feels like the vast majority of the architecture, gear, and items featured in the show - alongside all those other references, easter eggs, and cameos - are specifically designed to get you to head back to Boston, Boston's not ready to reward you for coming back.
As a number of folks who've decided to emerge from Vault 111 again have been reporting (thanks, TrueAchievements), Fallout 4's achievements on Xbox aren't doing what they should be. It seems like this has been an issue since the final days of March, since which point, the poor Sole Survivors on Microsoft's console haven't been able to be thanked for doing things like saving Preston Garvey, or playing Atomic Command on their Pip-Boy.
