Maskoi thanks. But didn't work. It's one of those weird zones where the place you zone in is 1000 units above the floor. I tried to adjust the Z (x) axis, and can get the zone mapped, and even showing up on "Show Navmesh"... but when you try to use /nav, you get an error like this "Could not locate starting point on navmesh: 3539.00 0.00 97.00"
