Double tagging of zone lines pok books etc still very present in all maps. Even maps that you suposedly fixed earlier =P

While the easiest way would be to use your onsite map viewer and just manually going trough each map ( once yo usee them they should be pretty obvious) and deleting double marks. maybe you could just make a rule of thumb.

Like only 1 pok book pr zone. Except in Tuxx forest.

Only 1 zone line to connecting zones.

just to get the double data down.
