Installing node-red-contrib-victron messes the flows file because when the module installs it creates a configuration node, and every time it restarts, it creates another with the same name.
Doing anything at this point just totally empties the flows file leaving you with a blank installation.
The developer has been notified on github months ago and they just ignore.
Any plans to make node-red proof of this problem? How about banning the node from the repo until it gets fixed?
I don't know why node-red allows for creating a duplicate node at first time. Not to mention blanking the flows file instead of erasing the culprit nodes.
