Are you playing on a progression server? Because the spell vendor probably doesn't yet exist.
If not on a progression server; check the map height/level settings and verify they are configured properly. Check map folder version / delete or move the current map folder a different location than the SOE folder then repatch the maps folder by using the EQ login patcher.
Layers - Each zone map has four layers. The first layer is reserved for default maps that we provide. You can create three additional layers for your maps. You will be able to turn on or off any of these map layers in any combination.
Visible - This determines which layers are visible.
◦Base – The base layer is the default map for the zone. ◦1 2 3 – This lets you view custom layers that you make.
