| Scenario | Action | | :--- | :--- | | You have never used Place Everywhere, but a mod requires Ppf.esm. | using xEdit (Method 2). The mod author made a mistake. | | You use Place Everywhere but don't care about Previs repair. | Delete Ppf.esm and ignore errors. Or use the dummy file method. | | You actively generate Previs repairs for large settlement mods. | Keep Ppf.esm and add it to your mod manager list. Load it high – just below the vanilla master files. | | You found Ppf.esm in your folder but don't remember creating it. | Safe to delete. It is an orphaned file. Re-run LOOT to re-sort your load order afterward. |
The file structure is broken, often caused by installing mods directly into the file rather than using a plugin (hard to do accidentally, but possible). Fix: Fallout 4 Ppf.esm
If you were previously using the Previs repair feature and you want that performance data back, simply regenerate the file. | Scenario | Action | | :--- |
