In case an artifact was deployed twice to the same repository under two different paths, in case the first deployed artifact will be deleted, it will not be possible to download the artifact until we will manually run the "Recalculate Index".
steps to reproduce:
1. deploy nuget package to the root of the repository
2. deploy the same package to another path in the repository (for example a/<package>).
3. try to install the package or run nuget list - everything will work.
4. delete the first deployed artifact
5. try to install the package or run nuget list - the server will not find the package
