Konami has provided new details regarding the recently discovered Metal Gear Solid V: The Phantom Pain save-corruption bug related to the character Quiet. The publisher says in a post on its website that it has identified the exact trigger for the bug. A patch to fix the problem is coming later, but for now, Konami has provided instructions for how to avoid it.

As stated previously, this bug can be triggered in Episode 29 and Episode 42 when Quiet is used as a buddy character. However, Konami now says you can still use Quiet during these missions and not run the risk of losing your save if you use the Butterfly Emblem through the mission. Alternatively, you can complete the mission and not lose your save by avoiding raising your Bond level with Quiet to Max.

Additional information regarding this save-corruption bug, including details about when the patch will be ready, will be announced “soon.” The problem is affecting all versions of The Phantom Pain.

“In the meantime, we apologize deeply for the problem and thank you for your continued patience as we work to resolve the issue,” Konami said.

Although The Phantom Pain received glowing praise upon release on September 1, the game’s launch was marred somewhat by servers issues that lasted days. These problems, which affected the game’s Forward Operating Base multiplayer mode, have now been largely fixed.

The Phantom Pain will grow next month with the release the game’s head-to-head multiplayer mode, Metal Gear Online for consoles. This multiplayer offering is coming in January 2016 for PC.

Earlier this year, Konami announced that it had started development on a new Metal Gear Solid game and was actively recruiting for the project. Meanwhile, series creator Hideo Kojima is expected to exit Konami, according to GameSpot’s sources.
