Victoria 3 1.15: Protect an Older Campaign Before Updating or Rolling Back

Choose the campaign's version before loading the save

Paradox's 1.15 release notice explicitly warns that old saves will not be compatible because the update changes the map and mechanics. It recommends backing up if the player wants to continue by backpatching. A failed load is not evidence the save is corrupt; first verify the game branch matches the save's origin.

The release announcement names 1.13 or 1.14 as the previous versions and says the 1.14 open-beta save is included. Treat this as a version-specific release instruction, not a promise that every later patch will preserve the same branches.

Branch-and-backup sequence

Use the exact storefront's version-management interface; Steam beta branch access is not interchangeable with Paradox launcher or other PC storefront instructions.

1. Exit the game and copy the campaign file to a separate dated folder; keep the original untouched.
2. Record the current game version/checksum and whether the save came from stable 1.14 or the 1.14 open beta.
3. In the same storefront, select the appropriate earlier version branch named by Paradox; if the branch is unavailable, stop and consult current official support rather than downloading an unofficial executable.
4. Launch the matching build and load only the backup copy. If it loads, continue that campaign on that branch.
5. For 1.15, start a separate campaign and avoid overwriting or transferring the old campaign file between branches.

Scope and player discussion

The linked Reddit thread is user-generated discussion around the update; it can help identify common questions but does not override Paradox's stated incompatibility. This checklist neither repairs a save nor inspects local files.

Before you play
