When you are in the new Uldum or Vale (and I suspect any other 'phased' 8.3 zones) your position is not on any of the existing maps. Your location is basically in the center of the 'world' maps. Zones not altered by 8.3 work fine.

The maps are not in Carbonite database so will not show until then..

@ChaoticWonder You can add the correct IDs there: https://github.com/mikepauer/Carbonite/blob/master/Data/Zones.lua

Ill add them in spare time. Now unfortunately im busy.

Vale and Uldum should be fixed 10a3934... but they show Overlays of maps before 8.3 ... there are no overlays for those in 8.3 files... need to find some workaround for this :/
