this mod needs the Vanilla UI, or one that is compatible.
We do not change the vanilla zombie targetting AI beyond adding the NPCs to the list, which is `ApproachAndAttackTarget class=EntityPlayer,0,EntityBandit,0,EntityEnemyAnimal,0,EntityNPC,0,EntityAnimal,0|` The player is the first priority of the zombies, so if it sees you, its going to go for you. Stealth wont help you if they are alerted and can see you.
