Moved Project stills reference to old path


I get packaing errors while having no error in the Output log. However, warnings stills reference to the projects previous path.
I moved the project out of my documents to the hard drive root due to the common ¨ long path error ¨. Funny thing ,it references to the ShaderBits-GDC_Pack Plugin which files were removed and its plugins deactivated.
Any one knows who to solve this issue?

Current path is C/UnrealSAS
