still facing this problem in 0.4.6 release

 node_modules/axios/lib/helpers/spread.js{ Error: Error transforming bundle with 'butternut' plugin: Cannot split a chunk that has already been edited (29716:8 – " {
      /*jshint noempty:false*/
    } while (")

it's axios this time

BTW, hope u can sync the release on rollup-plugin-butternut, thanks
