Problem/Bug Reset every restart

Hi guys i have a problem,

I create a faction server with my friend but every restart all faction are disband.

My faction plugin : https://www.spigotmc.org/resources/factions.1900/
My version : PaperSpigot 1.8.8


French (Ma langue)

A chaque fois que je redémarre mon serveur je perd toute les factions.
