Konami has revealed quite the major bug for the PlayStation 4 version of Metal Gear Solid 5: The Phantom Pain, so if you play the game on that platform, you better keep reading.

In the opening alerts when starting up Metal Gear Solid 5, Konami has posted an alert for the PlayStation 4 version of the game. The bug affects consoles that have multiple PSN accounts on a single system that renders your save file unusable by displaying the following message: “This save data cannot be used, as the relevant downloadable content was not found.” Konami says users will find it impossible to resume from a save file if this message is display.

Konami is working on a fix for this bug, although it suggests those with a single PSN account connected to their PlayStation 4 should play Metal Gear Solid 5.

If you happen to share your PlayStation 4 with other members of your family or with friends, this could be quite a devastating bug to come across. Hopefully Konami can figure a fix out before too many save files are rendered useless from this bug.
