inQizitOr, check the Editor\H5MMods\MAP_NAME folder. Unzip the archive of your map and compare it with the contents of that directory (e.g., using tools from Total Commander like "Synchronize Directories" and "Compare Files by Content"). Analyze the differences and try to combine the two into a working version.

I like your work with the terrain... Maybe smooth out the roads a bit so it's clear that you can walk on them, and not just hills. And in general, if there's a steep slope in a place where some object or a similar idea was planned, smooth it out.
It seems like you also know how to use the rnd tool, which is good.

Thank you for restoring my confidence! :o
Here's what I came up with, please rate it.

If I'm not mistaken, there's a way to import music; I saw a guide on importing models into the editor, and it seems music can be imported in a similar way. There's an option in the battle arena settings file to specify music.

Alternatively, you can assign it to a hero (it will sometimes play during battles involving that hero).

By the way, you don't need to import music (unlike sounds). You just need to put it in the folder with the rest of the game's music, which is usually called "music."
Then, in the advanced editor, you can conveniently select the "music" item from the drop-down menu, click "add," and enter all the necessary information (primarily the path to the music). This is similar to how you handle other objects like music.
After all these steps, you just need to assign the music to where you want it to play. As you correctly noted, heroes have "adventuremusic," but that's not what you need; it doesn't play during battles. There should be a separate option like "battleMusic" or "CombatMusic."
But I can't give you a definitive answer on this point; I don't remember the specifics.

What about the sound? Wouldn't it be easier to record sounds as music, since it's easier to integrate into the game?
