Heroes Battle

I renamed the map (removed the "1"), but no additional messages appeared when launching it (especially in German), meaning the scripts didn't activate. Did I do something wrong? Is there an original version available?

The map (a file with the .h5m extension) is an archive. Inside the archive, there's a folder: Maps/Multiplayer/Kampf der Helden 1/. You need to rename this folder. That is, unpack the archive, rename the directory, and repack it. I do this in Total Commander with simple clicks.
Just in case, I'm attaching the corrected map (I didn't change the archive name, as it doesn't affect anything).
