You will need to format your YAML correctly in order for me to find the issue. Use pastebin or a gist. What you have written is equivalent to what I have pasted below, and either won't work with the plugin because the indentation has been lost.

This is not a plugin issue. Its the inablity of the user to set the config.yml correctly. This should be closed.

@JackMD I am considering handling this more gracefully, which is why I left it open.

[Ifera]

@falkirks okay. Thats much better. The point is when will the user @Ben420x respond.

[falkirks]

@JackMD It's just about verifying that the structure of the YAML is correct before parsing it into ranks, and if it isn't give a warning.

@falkirks I used these settings of config.yml and these of groups.yml. They work flawlessly.,
