[NSFW] [Aryion] Certain gallery folders fail to download, making a mess of ~/gallery-dl/aryion/

[ghost]

Running into an issue downloading a few galleries, resulting in content failing to download and empty folders being created in ~/gallery-dl/aryion/

$ gallery-dl https://aryion.com/g4/user/BeanyStalk

Expected:
The entire gallery is downloaded within /gallery-dl/aryion//

Result:
This error appears multiple times during the download:

[downloader.http][warning] No filename extension found for MIME type 'application/x-comic-folder'

Content within these folders fails to download, and empty folders of the same name are created in the ~/gallery-dl/aryion/ directory.

The affected gallery folders have custom artwork instead of the standard folder icon, the folders without icons seem to download without issue. Not sure if that has something to do with it?

Affected galleries I've found so far:
https://aryion.com/g4/user/BeanyStalk (smallest affected gallery, easiest to test with)
https://aryion.com/g4/user/FlaxenSoftcloth
https://aryion.com/g4/user/Drazelleverse

Thanks,
