I loaded 12 songs into a new set list and saved it. I made some edits to a song and tried to save it and received a popup in Cantabile:
“The underlying compression routine could not be loaded correctly.”
It is happening with any song that I try to save in the set list. If I load the song outside of the set list on its own and save it it’s just fine.
Edit: Just found it, there was an older version of a song I accidentally loaded in to my set list that had a bunch of old v2 mappings for controllers that no longer existed and other weirdness in it. Removing that song fixed the issue. Just thought I’d still post it in case it’s helpful to anyone? I searched on the error here first and didn’t come across it.
