Applying Custom Instances
Instance Example (In the Main.xml)
<instance id="level_id">
<add file="levels/level_id/add.xml"/>
<include directory="levels/level_id">
<file file="world.world" type="generic_xml"/>
<file file="world/world.continent" type="custom_xml"/>
<file file="world/world.mission" type="generic_xml"/>
<file file="editor_only/editor_only.continent" type="custom_xml"/>
<file file="editor_only/editor_only.mission" type="generic_xml"/>
</include>
<packages/>
</instance>
```
With this setup you can work on the instance as a level without needing to move any files around
