Z-wave plus device keeps deleting it self

Does anyone experience a zwave plus or zigbee device deleting itself from the network?

Yes!:rage:

I have a few different Z devices that magically just disappears over the last years on my Vera Edge.
Support never find any solution (or really tried for that matter):cry:
Support: -Can you include device again?
Me: -Yes, but i don’t want it to disappear in the first place.
Support: -Ok, problem solved.
