I'um using spigot 1.8 with this Citizens version: http://dev.bukkit.org/bukkit-plugins/citizens/files/49-2-0-14-alpha-1-for-mc-1-8-1/ Commands work normally but when I use /npc create, it does nothing
Do you have Protocol Lib installed? Its a required dependency for 1.8. Let me know if you are still having issues.
Yes I have I found this working : http://ci.citizensnpcs.co/job/Citizens2/1199/artifact/target/citizens-2.0.14-SNAPSHOT.jar
