[B3.1] Stadium: simple map editor fails to start

[TMarc]

It says "Could not load the map!"
Cross-testing: Canyon works fine here.

Nadeo probably forgot to make a basemap (:

[TMarc]

It's not important for the editing experts though.
Instead of the simple editor I would recommend a map wizard

mood
mountains / lakes
primary block type
decoration or not
