Folders within Folders will get ignored if there are packs alongside with them.
resourcepacks
> pack 1
> pack 2
> pack 3
> misc (Folder)
> pack 1
> pack 2
> overlay (Folder)
> sky pack 1
> sky pack 2
> holiday (Folder)
> christmas pack
> halloween pack
With the example above, the overlay and holiday folders are ignored. They are seen as packs and with them not being packs and not having pack files, they are just not shown at all. If you could add support for this that would be awesome!
