For some odd reason, when I completed the second zone, and i have correctly setup the zone properly, the zombies spawn but they just move their head and won't move anywhere, neither they won't come to the player. When the player goes to the zombie, the zombie attacks, but when the player moves away, it does the same thing.

Help anyone?


Here's a screenshot that shows my problem, behind those zombies is another path that goes down.

Did you expand your navmesh into the new area? If not, give that a try.
Also the searchbar is a very helpful tool on this forum. I have found answers to many of my issues without needing to create a new topic.
Perhaps the floor is too steep?
