New game updates often break mods due to compatibility issues. If you want to play Fallout London, you will need to downgrade the game to the older version that came out before the next-gen update. While there is a Fallout London downgrader available on Nexusmods, players are experiencing multiple issues with it. To fix this issue, you can manually downgrade Fallout 4 from 1.10.984.0 to 1.10.163.0 (Steam) as follows.
How to Play Fallout London on Steam / How to Downgrade Fallout 4 Next Gen Update
First of all, you can purchase Fallout 4: Game of the Year Edition DRM-free on GOG. This allows you to skip updates you don’t like by turning off the game’s auto-update option or using the Rollback feature and choosing the game version you want. If you use Offline Installers, game updates are done manually and it’s always up to you.
However, if you don’t want to repurchase the game and want to continue with your Steam version, here’s how to start downgrading. Thanks to Pickysaurus on Nexusmods for sharing the exact steps. Keep in mind that this can be a complicated and technical method, so only proceed with it if you’re confident.
