Stable crashing on any release from exact artist page

[DarkVoyage]

Description

Normally I don't have any problems downloading any releases, I met some cases with duplicate names, when album is published twice under different slugs, it leads to a crash, but if you filter them out - it will be fine.

Here's a whole artist page is a problem, if you try any release - it leads to a crash.

I didn't know that original project is not maintained.
https://github.com/Nai64/BandcampDownloaderFixed resolves the problem

It's just that I don't find the time 🙁 but officially it's still maintained.

I'm reopening for when I'll be able to fix this. Thanks for the report.

Good to hear. But why not continue fixed edition if it already solves these problems and goes further?

Would be a good plan for future, if your downloader finally could do this https://github.com/7x11x13/free-bandcamp-downloader
