devices deleting from set-up

Added two devices an intermatic on-off, in-wall switch and an intermatic on-of module. saved, received confirmation of save. went to dashboard and back to make sure set-up is “sticking”. Confirmed.
Added two more devices, lost the first two.

I noticed when I setup my Vera, the system took a reset before my one module was recogized correctly.

It’s hard to know what caused it. But I created a bug report and we’ll try every combination of things to reproduce it:

Thanks guys. Your help is greatly appreciated.
