[Question] 'invalidate' event

[pharcosyle]

I'd like to know when the package is rebuilt so I can push updated stylesheets and to connected users. I tried listening to the 'invalidate' event thusly:

pipeline = convoy {...}
pipeline.on 'invalidate', ->
...do stuff

but the event seems to only fire once.
