Zigbee devices (bulbs, sensors, switches, outlets) randomly failing beginning March 2016

Does this sound familiar? This is from the day the Poltergeist started messing with my v2 hub.

Repairing Zigbee Mesh

I am trying to understand what may have caused my zigbee mesh to go haywire yesterday, after almost a year free of major incidents. I didn’t introduce new devices to my network of any kind. I did notice that a not used presence sensor got included automatically, which I thought was strange but not unheard of. Between yesterday and today, almost 80% of my sensors and bulbs dropped out , and those that are still connected are either extremely slow or sending wrong messages. Could this be a local issue in my home or something that may have happened on ST side? I did restart my hub twice in my attempt to ‘fix’ the erroneous messages I was getting from a presence sensor that is in my car. Also, I did open a ticket and am waiting for support to get back to me.
