Occasional npm run gulp-watch errors

[CloudNiner]

The process occasionally crashes with the error:

[19:19:19] Starting 'common:build'...
[19:19:19] 'common:build' errored after 43 μs

Possibly related? teambition/gulp-sequence#2

Workaround is to restart the process or manually run npm run gulp-development whenever static asset changes are made.

@CloudNiner I think teambition/gulp-sequence#2 may be related as you mentioned. I had the same error appear occasionally when a watch task would run a sequenced set of tasks.

I modified my usage of gulp-sequence to use the callback pattern as mentioned by @zensh here: teambition/gulp-sequence#2 (comment) - As far as I can tell, it's resolved my problem.
