not attacking anymore

u am using the defiant 36-40 path in drought lands. i decided to watch the bot to see how well the update was handeling. well when i went from 37 to 38 the bot stopped target mobs. i have a us jey board and everything is set correctly (obviously if when i hit 38 in the middle of a patrol it stop) now it will only attack if i am attacked and by passes everything else can i get feed back. i red other posts in here about issues and all my setting are set to the proper settings. so why wont my bot attack mobs anymore?

New update, 1.5
