As you can see, bestvideo[height<=?1080][ext=mp4]+bestaudio[ext=m4a] (137+140) isn't downloading.
Instead, bestvideo[height<=?1080][ext=webm]+bestaudio[ext=webm] (248+251) is downloading. Why?

[jaimeMF]

It's a bug, it will work in the next version. Thanks for the report!

Why?

The extension of the audio was being set to mp4, so bestaudio[ext=m4a] didn't match it.
