This makes sense but what if for instance your base straddles one or two chunks? Like if it were 18 blocks long it could be in 3 chunks?So if one way will require doing 15,000 block damage and another will only need 1000 the zombies will pick the lower number every time they can.
Then zombies spawning a chunk or two on the D-side of the fort might not path to the weaker A-side?
Or is their radius of pathing long enough to care?
