Commented Unassigned: MVC Scaffolding error, GenerateSeparateFiles=false [104]

IN VS.net 2013, when I try running the Add New Scaffolded Item -> "MVC5 Controller with views, using Entity Framework" and the model was generated using the single file option (GenerateSeparateFiles=false), I get the following Error:
"There was an error running the selected code generator: Object reference not set to an instance of an object."

Running the same model as multiple files seems ok.

Anyone else seeing this issue?

Thanks!
