We can say that Konami is quick to announce that there is a serious problem with Metal Gear Solid V: The Phantom Pain as the saved game file is broken, in a very advanced point of the campaign.
Metal Gear Solid V: The Phantom Pain – Save file bug spotted on all Platforms
The effect occurs when we play with Quiet as a sniper partner, mission number 29 or number 42, and so far, the only solution they have to offer is to avoid recruit for these tasks.
As has happened with the game’s release, with bug that prevented players with CPU without support for SSE 4.1 could play, Konami is working quickly to fix it, and perhaps also offers the possibility to join a beta via Steam, to test the upcoming patch.
The problem happens on all platforms, so it’s not a question of incompatibility, which will be solved shortly.
