# :icon-question: FAQ & Troubleshooting

#### 

**Advancements don't show up after creating them**

Run `/padv reload` to refresh the advancement UI. This re-initializes all tabs and shows them to all online players.

#### 

**The `L` menu doesn't update after `/padv reload`**

Close and reopen the advancement menu (press L again). The server has updated the data, but the client cache may still show the old view.

#### 

**`/padv apply` fails with "stale session"**

Your web editor session is outdated. The server data was modified externally (via `/padv reload` or in-game edits). Re-upload by running `/padv editor` again, or use `--force` to override.

#### 

**Error "An AdvancementTab with 'namespace' already exists"**

This is normal during reload and is handled automatically in v2.0+. If you see this, update to the latest version.

#### 

**GUI buttons don't work / items can be taken**

Ensure you have the correct version of the plugin. GUI title checks are version-specific. The issue was fixed in v2.0.

#### 

**config.yml has duplicated comments after update**

This was a bug in the ConfigUpdater's comment re-insertion logic (fixed in v2.0). Delete the corrupted config.yml and run `/padv reload` to regenerate it from resources.

**Can I use ItemsAdder/Oraxen textures?**

Yes, use `iconCustomModelData` for the advancement icon and `customModelData` for item types. Set the custom model data number that matches your resource pack configuration.

#### 

**How do I migrate from another advancements plugin?**

PremiumAdvancements does not have an import tool for other plugins. You'll need to recreate your advancements manually via the web editor or YAML files.
