That makes it even worse! They rewrote it and it's still seemingly not good enough, brings us back to the fact that they don't know what they are doing...
But that's besides the point because I didn't think we were really talking about AI in the sense of behaving like intelligent enemies - especially not in the case of DayZ where if anything the developer has the golden ticket, the get-out-of-jail-free card that zombies aren't supposed to be super smart in the first place... The "AI" in DayZ's zombies should pretty much boil down to:
* Shamble around the place in a "random" way
* If a noise source is detected head towards it
* If a player is close to you attack and follow
(and I guess the one thing we were actually talking about)
* Don't magically teleport about the place and clip through walls and other obstacles
It's not like they need to execute complex flanking behaviours and recognise when they're the last enemy standing in an area so they can react and retreat, they're zombies
