To add to this Garrett, in our tests here we found gigantic improvements in the response times when ghost/dead devices were removed from the mesh - to the tune of up to 30 seconds reducing in time in some bad cases, outlined here: FAQ: How to remove ghost devices from your z-wave and zigbee networks
I suspect resetting the hub may be doing that. I would recommend folks to try and clear out these ghost/orphaned devices from the mesh before resetting the hub.
