I have started creating a map using the map editor from build16.
However I now can no longer load the map into the editor. I get an Error message titled "Game data error".
The description starts with "allowed worker types: players 2" and ends with "[player 2] not found".
The map can be found at http://pholia.tdi.informatik.uni-frankfurt.de/~philipp/widelands/ as "Lesser ring.wmf".
Unfortunately I do not have a backup. Can this map be recovered? If yes, how?
Edit: As of 29th february of 2012, the link above no longer points to a broken map.
