Fallout 4 fans can't wait to get stuck into the long-awaited and highly anticipated mod that's been under development for years now, but, unfortunately, it hasn't been plain sailing for Team Folon. After the fan-made Fallout London mod had to delay its release due to Bethesda releasing an update for Fallout 4 which made the mod unplayable, the team is now faced with compatibility issues on the Epic Game store, meaning it can't be played via the launcher.
