Fixed | Slot and Size keys in default messages_it.yml, messages_fr.yml, messages_es.yml, and messages_de.yml files reported as malfunctioned due to the default value not being a number. This has been fixed in this update (thanks @_xXAndre50Xx_ for reporting the bug).
Fixed | Missing Info_Message key in default messages_it.yml, messages_fr.yml, messages_es.yml, and messages_de.yml files in sections Chat_Color_Selection and Name_Color_Selection.
If you do not use the English locale/messages_en.yml file and are on 1.0.4, you are strongly encouraged to update. I've uploaded the default message files for Italian, German, French, and Spanish below if you need an example of what these files should look like structure-wise. I apologize for the inconvenience!
