A quick PSA for those of you playing Metal Gear Solid V: The Phantom Pain: Konami has just released a brief statement about a game-breaking bug that they've discovered. If you take the sniper Quiet with you on either Mission 29 or Mission 42, there's a possibility that your save data will become corrupted and unusable.
The current advice for avoiding this possibility is obvious: don't take Quiet with you on either of those missions. Hopefully the "further announcements" Konami promises in the statement will include an actual fix. After all, I imagine a fair few people will be merrily playing through without bothering to read updates like this. And Phantom Pain is a long, long game. Corrupted save data could set a person back dozens of hours.
