This is a collection of several frequently asked questions and short tutorials about performing different tasks in the World Editor. This FAQ is by no means definitive; it serves as a basic reference and should assist mapmakers of all skill levels.

If your map has been corrupt, go look in the Maps/Test folder, there is always a backup of the last time you tested.
