Very strange one here.
I am running the latest Node-red on Ubuntu 16.04.
NPM is 6.2
I have a flow that sits in the background and pulls down the weather from Darksky - it is a direct cut and paste of one that Peter Scargill put up a while ago - all i have changed is to put my credentials in there.
This has been running fine for about 3 months now.
I just upgraded the Node-red-contrib-moment node to 2.02 - when i went to restart Node-red after that completed i received an error that -Darksky-credentials was not present and it halted my deployment.
When i checked it did look like the Nodes had been deleted from the palette.
So i readded and restarted node-red - see screenshot below - once i did that all good
My question is - 1) why would another node being installed delete something like this ? 2) Where do you go to troubleshoot - is it just the node-red logs ?
