Yes. Here’s an account of my previous issue. However, the cause was inconclusive. My hub is, and has always been on a UPS. May have been my bulbs causing the problem. They’re “Special”. 
Reboot is for sure the first troubleshooting action you should take. Rolling back like I did might not be a recommended action. I would contact support for their advice instead, should the issues persist after a few reboots.
