Late last week a game-breaking Metal Gear Solid V bug was discovered.
Konima has just announced via its official Metal Gear Solid V twitter account that the bug has been located and squashed.
We're happy to report that a fix for the Quiet/save data issue has now been implemented for PS4. The same fix for other platforms are coming

The bug in question: if you played with Quiet as your buddy during missions 29 or 42 there was a chance that your save file would be corrupted. Now Konami is saying that the PS4 version has been fixed. The PC version is being fixed as we type and all other versions will be patched forthwith.
Good news all round, and a pretty fast response time by Konami.
