That's a known issue with the standard driver. Refresh doesn't fix it. IIRC, Bryan's private driver worked for power loss although there was a timing issue surrounding the hub being down or rebooting during a power event. Refresh doesn't work for power in that one either. This and needing node testing were the principal reasons that I wrote this driver.
@Terk, with regard to the original question, I'm guessing that the C-3 isn't setting up the group or lifeline associations properly. Beyond my direct knowledge however. I've tested with the C-5 and C-7 only. Sorry.
