well these ideas are great but the zombies don't really need to be "fixed" excluding the part where they just instantly can walk through barb wire/wire fences, walls, and other player placed down obsticals while the player can't. but i personaly i think the second idea doesn't need to be fixxed as when they know exaectly where to go it's usually only one direction where they can move forword most of the time so they just run there and prob see you again and starts chasing again.
