Hi @CarlosTorch,
Again, thank you very much for testing! Now we know the root cause :)
So it looks like there is another mod, that is removing music/sounds from the core game ("automation" is from the core game).
So there are two solutions:
1.) Either the author of the other mod rewrites his mod, so that music from the core game is not removed (and just replaced).
2.) Or I can check in my mod, if core files have been removed, and ignore them or add them again.
Not quite sure, what is the best solution here, but I think it would be more logical, that mods don't remove core files from the game.
So replacing music files (like I do), or adding them, sounds fine to me, but removing them seems dangerous to me.
Either way, if this is important to you, you can try to find the conflicting mod,
by enabling the other music mods, one-by-one, until you get the error message :)
Then we know the conflicting mod, and then we have two options:
1.) Contact the other mod author, to replace "automation.ogg" instead of removing it.
2.) Or, I just mark his mod as conflicting mod in my mod config.
Again, many thanks for testing!
