When you mess around with Types/plugins/scripts/etc. sometimes you forget to delete all the nodes properly. And so you end up with a hidden node (of sorts), a "Could not load connections" warning, and the possibility of returning those nodes if you fix up your types etc. Which is great.
But sometimes you move on and don't want those nodes anymore. There should be a way to flush/clear away all these pseudo-nodes that exist only in-potential (and annoyingly in your Console)
