The references under the project named "CustomSquat" have a path issue. Its full path written on the properties tab says "The "Microsoft.VisualStudio.ProjectSystem.References.UnresolvedBuildDependencyProjectReference" reference could not be resolved." and gives an error message that says the same. I've tried to change the path, but it seems not allowed to change it straight from the properties tab. Its path is correct on ALL-BUILD, but when it comes to that particular project, it gives me an error. May I have any experts' advice to fix this problem? I tried changing True/False on the properties tab (literally tried every combination), and closing it and opening it again also didn't work. Run as Admin didn't work either. Please help me.
