Problème GroupManager

Bonjour,

Tout à l'heure, suite à une modification sur le fichier groups.yml, le plugin GroupManager est devenu inutilisable (aucun grade, et quand je m'ajoute à un groupe j'ai un message qu'il me dit qu'il y a une erreur, et de se reporter au fichier des logs).

Voici les logs :

mirrors:
# Worlds listed here have their settings mirrored in their children.

# the same user/groups files as the parent.
# Each child world can be configured to mirror the 'groups', 'users' or both files from it's parent.

- groups
swag:

# world2: (World2 would have it's own set of user and groups files)
# world3:
# - users (World3 would use the users.yml from world2, but it's own groups.yml)
# world4:
# - groups (World4 would use the groups.yml from world2, but it's own users.yml)
# world5:
# - world6 (this would cause world6 to mirror both files from world5)
