Just so I know I've got this straight, what exactly is the situation with the official map editor?

1) xolotl's map editor with a few changes and updates,

2) xolotl's map editor with a lot of changes such as resources from the previous games or,

3) A entirely different editor developed by BW ...

Is there a particular use for the anvil you find on the south side of the Mirkland Delta map?

If you need a specific item could someone just hint on where to get it.
