Build error on ember-cli-growl

So i was using ember-cli-growl when i found a build error related to growl-manager.css.

ENOENT: no such file or directory, stat '/Users/****/****/*********/tmp/concat_with_maps-input_base_path-http://ift.tt/2zqQYFs'

It seems the respected was on tmp/**/app/styles/components/growl-manager.css but the module called it in 'tmp/**/components/growl-manager.css'.

Anyone has experience this before?
