Pi4 Playlists/Logs broke things like Favourites screen - whappened?

I think this is a bug, but I can’t characterize it specifically-enough to feel like it should be logged (it happened over a week ago - should’ve made notes at the time, my bad), and it may be caused by me misusing Lakka.

What I did: On my Pi4, moved all my roms, dropped and re-created my Playlists, deleted all my Favourites. So everything should be gone from referencing the old locations…

but…

I couldn’t add things to the favorites list, and was getting weird behavior in general. Looked in debug console through SSH and found I was getting weird errors about log-files. So I deleted the contents of the “logs” folder in the Playlists and then everything was restored.

So what are those weird logs in the playlist folder? Seems like they do more than logging. What are they?
