Maps - Azeroth - Kalimdor - Silithus

Old Silithus

I found Silithus to be wierd. Even though most of the areas to be checked off are there and I received xp for discovering them they didn't "check off" for me. I had to talk to Zidormi by Valor's Rest and ask to see what Silithus used to look like and get the old map before any exploration actually counted. The new map seems to be automatially "uncovered" but nothing seems to count toward the exploration achievement untill you uncover it on the old map.
