### I installed mods, but they don't seem to be doing anything

* [#read-the-mods-documentation](#read-the-mods-documentation "mention") to find out how to access its features.
* [Did you accidentally launch in "No Mods" mode?](/modding-wiki/playing-with-mods/uninstalling-mods.md#launch-the-game-in-no-mods-mode-then-unsubscribe-from-mods)
* Check the tags on the mod.io page - is the mod not updated for this game version yet?
* [#check-your-log-files-for-error-messages](#check-your-log-files-for-error-messages "mention")  - sometimes mods can error in ways that don't get caught by Mod Reporter
* [#ask-for-help-on-the-discord](#ask-for-help-on-the-discord "mention")
* [Reporting Bugs](/modding-wiki/playing-with-mods/reporting-bugs.md)

### Can't join my friend's multiplayer game

See below.

### **`Game version mismatch` when playing multiplayer**

* Read the [general multiplayer notes](/modding-wiki/playing-with-mods/installing-mods/for-multiplayer.md)
* Ensure that all players have exactly the same mods installed
* If you're using mod.io interation, did it automatically update a mod on you? This means your installed mod version doesn't match the host's. One of you needs to update. Consider switching to [manual mod installation](/modding-wiki/playing-with-mods/installing-mods/on-game-clients.md#manual-file-management) to avoid the possibility of unexpected updates.
* [#ask-for-help-on-the-discord](#ask-for-help-on-the-discord "mention")

### Help, my game is crashing

The most common cause of this is installing broken or outdated mods.

* [#check-your-log-files-for-error-messages](#check-your-log-files-for-error-messages "mention")
* If you are playing from the Xbox Game Pass version, some mods can crash, even if they work on a normal PC install. Best solution if you want to play with these mods is to get the game on Steam.
* [Uninstalling Mods](/modding-wiki/playing-with-mods/uninstalling-mods.md)  - remove mods until the problem stops to track down what mod was causing the problem.
* [#ask-for-help-on-the-discord](#ask-for-help-on-the-discord "mention")
* Once you find out what mod in specific is the cause - [Reporting Bugs](/modding-wiki/playing-with-mods/reporting-bugs.md)

### "Mods" menu on the title screen does not load (`Failed to Fetch`)

* [Uninstalling Mods](/modding-wiki/playing-with-mods/uninstalling-mods.md#launch-the-game-in-no-mods-mode-then-unsubscribe-from-mods)  - remove mods until the problem stops to track down what mod was causing the problem.
* [#ask-for-help-on-the-discord](#ask-for-help-on-the-discord "mention")

### `Failed to create mod on mod.io: Api failed to complete the request`

* Try [uploading the mod manually](/modding-wiki/creating-mods/releasing-mods/mod-files-upload.md).

### `Command give does not exist!`

You did not properly install the chat commands mod, or something is preventing it from loading.

* Are you sure you've subscribed to Chat Commands and not just CoreLib.Commands?
* [#manually-subscribe-to-all-of-a-mods-dependencies](#manually-subscribe-to-all-of-a-mods-dependencies "mention")
* Try [uninstalling the mod](/modding-wiki/playing-with-mods/uninstalling-mods.md) then [installing it (and its dependencies) via another method](/modding-wiki/playing-with-mods/installing-mods.md).
* [#ask-for-help-on-the-discord](#ask-for-help-on-the-discord "mention")

### `Quantum Processor Error: Command <something> could not be found.`

* Run chat commands in the game's chat window, not the debug Quantum Console. If you still want to use the quantum console, prefix your commands with the word `chat` so they are executed as chat commands.

## Fix Approaches

*This section contains troubleshooting approaches for the above problems to link to.*

### Install the Mod Reporter mod to check for loading errors

The **Mod Reporter** mod provides a GUI on the main menu to view the current state of your installed mods and see any issues easily.

{% embed url="<https://mod.io/g/corekeeper/m/mod-reporter>" %}

### Check your log files for error messages

Take a look at your [game log files](/modding-wiki/concepts/important-folder-paths.md#log-files) to see if any mods are reporting errors.

### Read the Mod's Documentation

Check for directions on how to use the mod, known issues, etc. on the mod's page on mod.io.

### Manually subscribe to all of a mod's dependencies

The game's mod.io integration often fails to download mod dependencies. Visit the mod's page on the [mod.io website](https://mod.io/g/corekeeper/) to see what they are and manually subscribe to each of them.

### Ask for Help on the Discord

Join the [Core Keeper discord](https://discord.com/invite/corekeeper) and ask for help in the `#modding-help` channel. Make sure to:

* Include your [log files](/modding-wiki/concepts/important-folder-paths.md#log-files)! It will be the first thing people ask for if you don't provide it.
* Mention what mods you are using.
* Say what you expected to happen, and what actually happened. Screenshots help too.
* Say if you're playing in singleplayer, multiplayer, or a dedicated server, and if you're the host or the client.

Remember to *communicate what you fixes have already tried*. People are a lot more willing to help if you make it clear you've already put in some effort!
