file watcher pyScss

I used to use pyScss 1.1.4 and scss-tools 0.1.0 to watch file changes.
I tried to upgrade to pyScss 1.1.5, but scss_tools no longer works. So I had my hopes up for the new file watcher feature.
I've got it almost running, except for sprites.
The path to the images is not found.

ERROR: Nothing found at '/products/index/*.png'

Has anyone configured file watcher to use just pyScss to auto transpile scss? What are your settings?
