You've spent forty hours sneaking through the Afghan desert. You’ve fulton-extracted enough goats to start a zoo. Then, it happens. You hit Mission 22, "Platform Retrieval," and suddenly Metal Gear Solid V: The Phantom Pain decides it doesn't want to be a game anymore. It wants to be a loading screen.
The MGS5 Mission 22 bug is a notorious piece of gaming history. It’s not just a glitch; it’s a gatekeeper. For many players, especially those returning to the Fox Engine’s swan song years later, this specific error represents a hard stop that Konami never fully polished away for every platform. It usually manifests as an infinite loading loop or a hard crash right when you're supposed to be defending Mother Base from Mosoko's R&D team.
It’s frustrating. Honestly, it's soul-crushing. You’re finally getting into the meat of the FOB (Forward Operating Base) mechanics, and the software just gives up.

What's Actually Happening During the Mission 22 Crash?
Let’s get technical for a second, but not too boring. When you start Mission 22, the game triggers a massive shift in its logic. It moves from being a single-player, offline experience to something that desperately wants to talk to Konami’s servers. This is the moment Mother Base becomes "online."
The bug is almost always tied to a handshake failure. Your console or PC is trying to verify your save data against the server's records of your FOB. If there’s a discrepancy—maybe you used a mod, or maybe your internet flickered at the exact millisecond the game checked your "Gmp" balance—the game panics. Instead of giving you an error message, it just sits there. Forever.
I’ve seen reports on Steam forums and old Reddit threads where people claim it’s a hardware issue. It’s not. Your GPU is fine. Your PS5 isn't dying. This is a legacy code conflict. Specifically, it often involves the "Quiet" or "Butterfly" emblem bug if you’re playing an unpatched version, though that's usually associated with Mission 29 and 42. In Mission 22, the culprit is nearly always the server sync.
Why Does This Keep Happening in 2026?
You'd think a game from 2015 would be "solved" by now. The reality is that server-dependent games age like milk if the infrastructure isn't perfectly maintained. As Konami shifts resources, the stability of the MGS5 backend fluctuates.
If you're playing the Definitive Experience, you have a better shot at avoiding this, but even then, the MGS5 Mission 22 bug lurks. Players on PC have it the worst because of how the game interacts with the Steam Cloud. If your local save says you have 500,000 GMP but the cloud thinks you have 499,999, the Mission 22 trigger might just hang while trying to reconcile that one-point difference.
Real Ways to Fix the Infinite Loading Screen
Don't delete your save. Seriously, don't do it yet. There are a few "shamanistic" rituals that actually work because they force the game to reset its connection parameters.
First, try the "Offline Shuffle." This sounds stupidly simple because it is. Before you start the mission, go into your pause menu and select "Disconnect." Play the mission entirely offline. Most of the time, this bypasses the server handshake entirely. Once the mission is over and you’ve reclaimed your platform, you can reconnect.
If that doesn't work, we have to look at your staff.

The Staff Capacity Glitch
Sometimes, the bug isn't the internet. It’s your people. Mission 22 involves a scripted takeover of your R&D platform. If your R&D department is 100% full, the game occasionally glitches out when trying to "displace" your staff for the mission’s scripted events.
Go into your Staff Management. Fire a couple of low-ranking C-grade losers. Give the game some "breathing room" in the database. You'd be surprised how often clearing out five or ten staff members suddenly allows the mission to load. It's like the game's internal spreadsheet is too full to add the "intruder" entities.
- Step 1: Back up your save file manually (if on PC, copy the
remotefolder). - Step 2: Go offline in the game menu.
- Step 3: Fire 5-10 staff from your R&D team.
- Step 4: Restart the game.
- Step 5: Enter the mission immediately from the ACC (Aerial Command Center).
The "Quiet" Connection
While the MGS5 Mission 22 bug is primarily a Mother Base/FOB issue, it occasionally gets tangled with the famous Quiet bug. Back in the day, Kojima Productions had to release a literal emergency PSA because having Quiet as your buddy in certain missions would corrupt your save.
While Mission 22 is a solo mission (you're forced to play as Snake on Mother Base), the game still checks your "Buddy Bond" levels in the background. If you’ve been using mods to keep Quiet available after she's supposed to leave, or to bring her into missions she shouldn't be in, Mission 22 will catch you. The game’s logic check sees a "ghost" buddy and hits the brakes.
What if You're on Console?
PS4, PS5, and Xbox players have fewer tools. You can't just go into the directory and delete a .dll file. For you, the fix is usually a "Power Cycle" plus the Offline method.
- Shut down the console completely.
- Unplug the power cord for 30 seconds (this clears the cache).
- Boot up, but stay disconnected from PSN or Xbox Live.
- Launch the game and try Mission 22.
If you’re still stuck, check your "Waiting Room." If you have hundreds of staff sitting in the Waiting Room, the game struggles to process the reorganization that happens during the FOB tutorial that follows Mission 22. Clear the clutter.
Is it a "Game Over" for Your Save?
Rarely. I’ve helped people troubleshoot this for years, and it's almost never a permanent corruption. It’s just a traffic jam. The game is trying to do too many things at once: it's loading a map, it's checking a server, it's calculating staff bonuses, and it's trying to trigger a cutscene.
If you're on PC and absolutely nothing is working, you might need to use a "Save Editor" to manually flag Mission 22 as complete. It’s a last resort, and it feels like cheating, but it’s better than losing 50 hours of progress because a decade-old server didn't like your IP address.
Why Konami Never "Fixed" It
The truth? They did. Mostly. But the Fox Engine is a complex beast. When Hideo Kojima left, the institutional knowledge of how that engine handles memory management went with him. The patches that exist for MGS5 Mission 22 bug addressed the most common triggers, but they couldn't account for every weird edge case involving modern high-speed internet or backwards compatibility on newer consoles.
It’s a ghost in the machine. A remnant of a messy development period.
Practical Steps to Move Forward
If you are staring at a black screen with a spinning circle right now, take a breath. You aren't alone. Follow the "Offline Shuffle" first. It’s the highest success-rate fix available.
Next, look at your GMP. If you have an absurd amount of "Online" GMP (the stuff in the globe icon) but very little "Offline" GMP, the game might be getting confused about whether you can actually "afford" the mission's deployment costs. Try to sell some precious metals or plants to boost your offline currency. It sounds crazy, but balancing your books can actually un-stick the loading screen.
Finally, make sure your game is updated to the latest version. Even if you think it is, "Verify Integrity of Game Files" on Steam. Sometimes a single corrupted texture on the R&D platform is all it takes to crash the mission.
You’ve got a world to save and a revenge story to finish. Don't let a botched server handshake stop you from experiencing one of the best stealth games ever made. Get offline, fire some staff, and take your base back.

Once you clear Mission 22, the world of FOBs opens up. It’s a bit of a grind, but it’s where the real endgame begins. Just remember to keep manual backups of your save from here on out. You never know when the Fox Engine might decide to take another unscheduled break.
To ensure this doesn't happen again, always finish your session by returning to the ACC rather than just quitting from the field. This forces a clean save that is less likely to trigger a sync error the next time you boot up.
