La réponse est sur le site de Spigot pourtant, tu as téléchargé sans lire les news.

[quote]This thread marks the release of another Spigot update. The following changes have been included.
Only force player list name update if it has been modified. Previously we would always send it which would overwrite any prefixes / suffixes / modifications made as a result of scoreboard manipulation. As of 1.8 both scoreboard and custom player list names cannot both apply at the same time, we will use the custom scoreboard name unless a plugin has explicitly set a player list name.[/quote]
En gros sur la 1.8, la player list et le scoreboard ne peuvent être appliqués simultanément, donc ils utilisent une player list personnalisée pour le moment en attendant qu’une plugin prenne cela en charge.
