Treat rollback as a controlled branch change
The cited instructions are a historical example tied to a particular update. The current client and current announcement determine whether that branch still exists and whether it suits your campaign.
- Write down the current build, branch, mod list and last known-good state.
- Back up saves separately before switching; keep one untouched copy and avoid loading/saving it on a different build.
- Read the current official announcement to identify the exact branch/version under discussion.
- In Steam Properties > Betas, inspect the available choices; do not assume 1.5.1.7 remains listed just because an old note used it.
- Change only if the exact branch is available and the mod author identifies it as supported; verify Steam has finished updating before launching.
- If the branch is unavailable or behavior differs, return to the current supported build through Steam and ask for version-matched help.
| Decision point | Proceed only when | Stop when |
|---|---|---|
| A guide recommends rollback | Exact branch still appears and matches the mod's support note | Branch is absent or the guide omits the version |
| Valued campaign is involved | Separate backup exists | Only copy would be opened on another build |
| Steam is changing files | Download has fully completed | Client still says updating |
| Issue persists after switch | You can describe a controlled before/after | You cannot separate branch from mod changes |

A forum answer about 1.5.1.7 may not apply to another patch or current branch selection.
- List current and proposed versions, plus Steam branch label.
- State the mod and its supported versions.
- Describe whether a separate save backup exists; never share private data publicly.

Frequently asked questions
Is 1.5.1.7 the recommended current version?
No. The cited announcement used it as a rollback example at that time; check today's branch list and mod support notes.
Will rollback repair a damaged save?
No such guarantee is documented. Preserve the save and seek current official help.
Does this apply to GOG or consoles?
The described click path is Steam-specific; other platforms require their own current instructions.
