Gulp.src isn't returning any files, or something?

Question

I was working on a new project at home last week and now I am in the office I am having no luck with Gulp.

There are no errors when I run Gulp but it isn't creating any files, I tried using Gulp-tap to see if anything was getting piped but its not. I am sure I am in the correct cwd and the file exists, but I have no luck. The task is also been run, confirmed by console.log'ing.
