I am not sure how this happened or what could have caused this, so I will give you the sequence of events.
Two RPis running the same flow, connected to the same network.
I install another RPi running the same image that I made from one of the running RPis.
Upon power up of the new RPi, the resolution was too small, so I had to reset the resolution. Note, that chromium was already started and showing my node-red dashboard.
I change the resolution then reboot.
After reboot, Chromium did not autostart. So I manually opened it.
I was prompted with "Chromium has detected another process running at host (raspberrypi). Would you like to unlock and take control?" I clicked Yes and when I navigated to my dashboard, I was faced with the "Please add some nodes to your dashboard".
Checking the node-red config, the entire flow is gone! Dashboard settings, configuration nodes, everything is gone.
Thinking ok, something happened...I will just copy the flow from my other RPis.
I logged into the other RPis I have running and the same thing. All of the flows are gone!
Any ideas how this could have happened? Luckily, I have a backup, but still...this is kinda scary.
*EDIT: I did find a bug in Chromium, where if you change your hostname it won't open and prompt the user with "The profile appears to be in use...".
