*-close classes were removed from build

[theRenard]

got this weird issue, if a class ends with -close it is removed from the built .css

index.scss

.mfp-close {
    width: 100px;
    height: 100px;
}
.test-close {
    width: 100px;
    height: 100px;
}
.close {
    width: 100px;
    height: 100px;
}
.test {
    width: 100px;
    height: 100px;
}

generated styles.css

.close,.test{width:100px;height:100px}
/*# sourceMappingURL=styles.eae04a2f42f80581e776.css.map */
