You may not have the zone files, here's a playermade version.
Edit: Reason being that some clients don't come with this, according to some friends of mine whom have been guides on EQ you had to get these files exclusively from Sony, I don't know the authenticity of this, but it seems like a viable reason.
ALSO: NPCs may spawn under the map, so do #aggrozone and #spawnfix them.
