Hello everybody !! I have update Spigot 1.8 to 1.8.8. I installed the plugin Citizens ( ver. 2.0.16 ) and it work. And I installed the plugin Sentry ( see the version : http://ci.citizensnpcs.co/job/Sentry/28/ ) and it work !! But, here is my problem, I create a npc with trait "sentry", but when I attack him, he don't move for 5 secondes or plus, and after attack me. So, my problem is sentries are slow when I attack them. Thank. Sorry, I'm french.
