Confirm the exact Rockstar diagnosis
Rockstar's article is specific: the game is Red Dead Redemption 2 Story Mode on PC, the message is 0x1000012c, the save is located within OneDrive, and the local and cloud copies are out of sync. A different code or Red Dead Online disconnect is outside that stated diagnosis.
| Check | If yes | If no / unsure |
|---|---|---|
| Is this PC Story Mode? | Continue to the exact error check. | This article may not apply; use support for your platform and mode. |
| Does the message show 0x1000012c? | Compare your OneDrive setup with Rockstar's article. | Do not apply the OneDrive diagnosis to another code. |
| Is the RDR2 save in a OneDrive-synced location? | Inspect sync status without moving or deleting the save. | The support article's stated cause may not match; contact Rockstar if the exact error persists. |
| Do local and cloud copies report pending/conflicted sync? | Use Microsoft's current sync-resolution instructions and preserve copies first. | Do not force an overwrite; record what you observe and ask Rockstar support. |

Protect the save before repairing sync
This is a conservative ordering around Rockstar's stated cause. It does not resolve conflicts automatically and does not claim a particular copy is valid.
- Write down the exact code, PC/Windows context, Story Mode, and whether the Documents/RDR2 path is under OneDrive. Do not post a save file publicly.
- Pause before deleting, renaming, relocating or restoring either copy. If you already have a safe backup method, preserve a separate copy before changing sync state.
- Check OneDrive's current sync indicator for pending sync, pause, conflict, or sign-in status; do not guess which copy is newer from timestamps alone.
- Follow Microsoft's current OneDrive sync troubleshooting from Rockstar's article. Let the intended sync finish before launching again; avoid editing the save path at the same time.
- Retry Story Mode and note whether the exact error changes. If it remains, or the save is not in OneDrive, contact Rockstar Support with the exact message and non-sensitive steps.

Use community posts only as comparison clues
A forum post about cloud sync may concern Steam Cloud rather than OneDrive, a different Windows profile, or a different RDR2 error. Include the exact code, game mode, storefront and OneDrive state when comparing reports. Never share Rockstar credentials, recovery codes, or a private save with strangers.

Platform limits and next step
The cited Rockstar page is for Red Dead Redemption 2 PC Story Mode and this exact code. It does not establish that a console error, a Red Dead Online disconnect, Steam Cloud conflict, or another numeric code has the same cause. If your setup does not match, stop this checklist and use the support page for the exact mode and platform.
