Hi,
so the issue is the following:
when I try to "install" or "restore" a NuGet package that is hosted on GitHub, it always installs the latest version of the package rather than the (older) version that I specified via packages.config or via the Editor Window.
The package is hosted on a company private GitHub repository and it requires authentication via GitHub token. The issue is not present if I execute the same commands via the official dotnet CLI in a .Net empty project so I'm pretty sure the package is available in the registry.

Operating system: Windows 10
NuGetForUnity: 4.3.0
