Auto-retrieve artwork stored in the parent / same level folder

[redwing]

Noticed a new bug since a few weeks ago.

For a box set like this

<Album 1> - Tracks
<Album 2> - Tracks
<Album 3> - Tracks
Cover.jpg

when you delete Cover.jpg in the parent folder and rescans the box set, it searches an image in sub-folders and replaces the deleted image with the first found one.
So if <Album 2> happens to contain folder.jpg, then now the entire tracks are linked to that image instead of the deleted Cover.jpg.

Regarding the issue reported above, rescanning such albums again sometimes change those wrong images to another wrong ones that can't be linked to by auto-retrieve settings.
As I said, this bug occurs only when an existing linked files get removed. MB seems somehow to try to fill in the removed image with something else disregarding the settings.

The reported bug still persists.
BTW I found a workaround. Never delete an linked image outside MB and always delete them using artwork manager to prevent the bug to occur.
