It appears that there is a potential issue affecting some PlayStation players who are trying to access the Fallout 4 update. Specifically, there are reports of PlayStation Plus users encountering problems.
However, developers have indicated that this may be a mistake and they are investigating the issue. For those playing on PC and Xbox, the update seems to be proceeding smoothly, though it remains to be seen if any new issues will arise with the updated game.
The delay of Fallout London due to the update is already causing disruption, but there is hope that the problems with the PS Plus version will be resolved promptly.
