A slight issue has arisen with the Caledon Directory, in that, ahem, it doesn't work. Well, to be fair to myself it does work in Caledon I, and it does produce a map with all of the landmarks placed appropriately - it is just that when one touches a landmark outside of Caledon I and opts to Teleport, one does not actually go there.
The reason for this is simple. The Directory holds a number of landmarks, which as I am sure you are aware are a specific and special type of object in Second Life.
