I have added a new command to allow you see the output of all your set messages in game at once.
In doing this I discovered a few messages that weren't being displayed properly but that has now been fixed.
Getting a fresh version of the Messages.yml file is required to fix the issue.
Steps to repair:
1. Download a copy of your old config.
2. Delete the old config from the server.
3. Reload the plugin.
4. Copy and paste the messages you have set over to the new config.
