Title says it all. When you save a previously tagged album with modified capitalization of some tag value the filename script uses, the new capitalization is not reflected in the destination path. This is the case for both folders and files in place. However, if a file is being moved out of its original location, the file's name does change to reflect the new capitalization.

Steps to re-produce:

1. Add a previously tagged album to Picard.
2. Change the capitalization of any tag value that is used as part of the filename script in use. For example, the album title if that forms part of the destination path as dictated by the filename script in use.
3. Click "Save".
