Multiple SVG sources issues

[mathijsrave]

For my project I'd like to use gulp-iconify, but I'm running into issues when I'm trying to run multiple instances of the gulp task with the 'runSequence' plugin.

gulp.task('default:iconify', function (callback) { runSequence(['iconify:sts', 'iconify:sbc', 'iconify:stu', 'iconify:itd', 'iconify:stb', 'iconify:vde'], callback ); });

I think the issue is that the task gives a callback after the iconify tasks are started instead of finished. Is there a workaround for the lack of callbacks? Thanks in advance
