Game Mechanics: Camo Not Working?

[Fleetwood]

I was on my lvl 39 Ranger running through West Freeport Camo'ed.
I am KoS in West Freeport but I'm fine in North, so this is nothing new to me.
Only problem was that this time I agroed the guards at the gates and they took a couple swings at me but missed. Since they missed it didn't break camo but I was continuing to agro more indifferently conned mobs. I noticed the guards model has been changed and I dont know what other changes have been made but thats not right I'm pretty sure.
