# Troubleshooting

## Troubleshooting

Use these checks before changing configuration values.

### The plugin does not load

Confirm the server uses Paper 1.21+ and Java 21. Check the startup log for dependency errors. Run `/sm` after startup to verify access.

### A mine does not reset

Confirm the mine is enabled with `/sm enable <name>`. Then inspect its time or percentage reset requirement in `/sm edit <name>`.

### Resets affect server performance

Lower `max_milles_per_tick` in `config.yml`. This reduces the work per tick and extends reset duration.

{% hint style="warning" %}
Do not raise `max_milles_per_tick` without monitoring server tick time.
{% endhint %}

### Custom blocks do not appear

Install the provider before starting SimplyMines. Restart the server after adding ItemsAdder, Nexo, or CraftEngine. Confirm the configured block ID matches the provider's registered ID.

For common questions, see [FAQ](/simplymines-docs/introduction/faq.md).

# 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 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://simplymines.gitbook.io/simplymines-docs/introduction/troubleshooting.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.
