"0 files busted" although it did work

[lhtdesignde]

Hey, when I run cacheBust it says "0 files busted" although it did indeed update one file and added a hash. What is this supposed to tell me?

config:

    cacheBust: {
      options: {
        algorithm: 'md5',
        length: 20,
        separator: '-',
        deleteOriginals: true
      },
      css: {
        options: {
          assets: ['<%= paths.dist %>/stylesheets/*']
        },
        src: ['styles.css']
      },
    },
