I'm creating some guard/bouncers on my server. I've set the radius, addflags, equipped, and added a line of humorous text to the four I've made. Come nightfall, they don't attack any of the mobs I've added flags to. They are all set aggressive. All they do is stand there. They don't look at me, (and no, it's not turned off) and they don't talkclose either(and yes it is selected). I just happened to look at my server log and seen the warning message on there and thought, hmm, could that be it? I'm running vista 64 SP2, its x86, Hamachi 2, java version 1.7.0, java SE runtime Environment build 1.7.0-b147, java HotSpot 64-bit server VM build 21.0-b17, mixed mode. The plugins i have are AuthMe, ChatManager, CivilizedSpawn, CreeperHeal, MotherNature, Iconomy, ModifyWorld, PermissionsEx, Lockette, noEnderman, and WorldEdit. Here's the server log with the warning, and thanks for the help.
