Ran --precision command with wrong input file, breaks the css output file

[JanaVanMaele]

I use gulp-sass to compile my css. Now I wanted to change the precision setting of sass and I ran
sass --precision 10 app/sass/**/* app/main.css
I used a wrong input file, my bad, and this command gave an error in my terminal.

Error: Undefined mixin 'type'.
        on line 21 of app/sass/components/_components.booking-timeslot.scss, in `type'
        from line 21 of app/sass/components/_components.booking-timeslot.scss

The type mixin exists and I had to run
sass --precision 10 app/sass/main.scss app/main.css
instead of
sass --precision 10 app/sass/**/* app/main.css (in this case the mixin does not exist)

If I now run my gulp sass command, which worked fine before, this error still occur in my generated css output file, but my gulp sass command gives no errors.

main.css

body:before {
    white-space: pre;
    font-family: monospace;
    content: "Error: Undefined mixin 'type'.\A on line 21 of app/sass/components/_components.booking-timeslot.scss, in `type'\A from line 21 of app/sass/components/_components.booking-timeslot.scss\A \A 16: &__timeslot {\A 17: text-align: right;\A 18: }\A 19: \A 20: &__start-hour {\A 21: @include type('body', 'high emphasis');\A 22: }\A 23: \A 24: &__end-hour {\A 25: @include type('meta', 'medium emphasis');\A 26: }";
}

Can anyone explain what I am doing wrong or how I can undo the --precision command with the wrong input file?
