# Errors while loading a map

If you are trying to load a world from a lower version (ex. 1.8) to a higher version (ex. 1.21) and it isn't working, you have to convert that world by yourself. It's nothing hard.\
 

The first step is to get the lower world into your singleplayer worlds (<mark style="color:$primary;">%appdata% -> .minecraft -> saves</mark>).\
After that, join to the world in singleplayer with the Minecraft version you want the world to have.&#x20;

Like if you join there with 1.18, the world will be converted to 1.21. After all that you successfully converted it.\
Now get the world from saves and put it on your server.

**Good to know:** You can create a support ticket, describe your problem and, send proof of purchase so that you can be provided with the correct world download&#x20;
{% endhint %}

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://wiki.breadbuilds.com/minecraft-map-issues/errors-while-loading-a-map.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
