FixupRedirects via 4.17.1 ResavePackages commandlet problems with moved umap files

I have created level umap ( Master.umap) referencing a sublevel umap ( SubLevel.umap ) in same folder /Game/Maps/Foo . Then later on I moved the sublevel umap into a sub-folder /Game/Maps/Foo/Bar under the parent folder , and I notice a redirector file ( SubLevel.umap ) of very small file-size was created automatically under the /Game/Maps/Foo for the moved sublevel .

I then run ResavePackages commandlet with switches -FixupRedirects -ResaveDirectRefsAndDeps -IgnoreChangelist -AutoCheckIn -AutoCheckOut -PROJECTONLY -NODEV .
A log was obtained and it shows :

LogContentCommandlet:Display: Loading …/xyz/Content/Maps/Foo/Master.umap
LogContentCommandlet:Display: Resaving package […/xyz/Content/Maps/Foo/Master.umap] (UE4 Version: 517, Licensee Version: 1 Saved UE4 Version: 517, Saved Licensee Version: 1)
LogContentCommandlet:Display: Correctly saved: […/xyz/Content/Maps/Foo/Master.umap].
LogContentCommandlet:Display: Can’t delete redirector […/xyz/Content/Maps/Foo/SubLevel.umap], unsaved packages reference it

From the editor I can see that only /Game/Maps/Foo/Master is referencing it .

Why the commandlet failed to delete the redirector file ?

Any luck? It might be that the level with the redirect is still referenced in memory. Try unloading the maps, resave all and then run the command again. Also you can run it in the editor but it’s the same thing. If you renamed either of the maps before doing this it could have lost one of the the references.
