Current questions and answers regarding the map editor.

I experimented a bit with arenas in connection with my latest map. But I didn't create my own; I just found a standard one, and I only needed it to have absolutely no obstacles.
However, I did look at arenas in the editor. I might be wrong, but it seems that the battlefield itself isn't always in the same place. This is evident, at least, because the battlefields are always the same size, while the maps for them vary greatly in size.
