Te comento algo que vi el otro día.
Tengo todos los paquetes de música que has creado, unos días atrás, vi en el portal de actualizaciones, que había una actualización de uno de tus paquetes de música, pero dentro del juego, no me aparecía como para actualizarlo, por qué habrá pasado eso ?

Como siempre, alucinante toda la música y me encanta!

I wanted to tell you something I noticed the other day. I have all the music packs you've created. A few days ago, I saw on the updates portal that there was an update for one of your music packs, but it wasn't showing up in the game as an update option. Why did that happen?

As always, all the music is amazing, and I love it!

I'm not Preceti, but most likely it was a 2.1 update and you're still on the "stable" 2.0.77 version. Some people like to use the newest "experimental" version of Factorio, which is currently on 2.1.17 ... so some mod creators are beginning to transition some of their mods into the 2.1 version so they can still be used. They will show as an update, but because you don't have the 2.1 version of Factorio it won't download because you can't use the 2.1 version of the mod with the 2.0 version of the game.

I believe the reverse also applies. If you're on the experimental version and they update the mod for the stable version, because of the version mismatch (2.1 version of the game vs 2.0 version of the mod) you still will not be able to download or use it.
