# Reset options

Because the pack is using Config Manager or YOSBR, your vanilla options and most of the mod ones will not change when you upgrade. This is done so that you can upgrade without having to reconfigure your options all the time.

However, at some point you may still want to do that in order to get the latest changes.

{% tabs %}
{% tab title="Modern versions" %}

1. Launch the game
2. Go to `Mods` -> `Config Manager` -> `🎛️`
3. If you want to *apply latest changes* but keep configs for added mods, select `Update modpack's configs`.
   * If you want to *delete all configs* and start fresh, select `Reset modpack's configs`.
4. Close the game and start it again. See if it works.
   * If you got an error (especially on alpha or beta versions), start the game again to ensure configurations are properly applied.
     {% endtab %}

{% tab title="FO 10.3.1 and older" %}

1. Open the modpack folder:

{% tabs %}
{% tab title="CurseForge App" %}
Right click on the modpack tile → `Open Folder`
{% endtab %}

{% tab title="Modrinth App" %}
Right click on the modpack tile → `📂 Open folder`
{% endtab %}

{% tab title="Prism Launcher" %}
Right click on the instance → `Folder` → `.minecraft`
{% endtab %}

{% tab title="MultiMC" %}
Right click on the instance → `Minecraft Folder`
{% endtab %}

{% tab title="Minecraft Launcher" %}
Click `Installations` → hover on the instance → click `📁`
{% endtab %}
{% endtabs %}

2. Delete the `config` folder
   * If you prefer, also delete `options.txt` which stores vanilla options
3. Download [your version of the modpack again from Modrinth](https://modrinth.com/modpack/fabulously-optimized/versions)
4. Rename the file to `pack.zip`
5. Open the file you renamed, go to `overrides`
6. Copy/extract the folder `configs` out to the modpack folder you previously opened
   * You may delete the `pack.zip` after you're done
7. Launch the game. Modpack's defaults are now applied!
   {% endtab %}
   {% endtabs %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://wiki.download.fo/update-instructions/reset-options.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
