Old Sample Scene Behavior Change

[mitchfx]

Here's a great example by YUZURU SHIGIHARA of TyFlow grains, clustering and bindings to do a snow effect.  For some reason the cluster binding in provided scene doesn't seem to behave like the video so I'm wondering if early changes to bindings logic, etc. might have broken things.  I've been digging in the graph trying to find the culprit but still scratching my head.
