When threejs release 173 playground run and save on the screen nodes to nodes.json … i don’t load after that nodes.json file to playground screen… in console i get this error →

Uncaught TypeError: node.setEditor is not a function
at NodeEditor.add (NodeEditor.js:96:8)
at NodeEditor.loadJSON (NodeEditor.js:204:9)
at reader.onload (NodeEditor.js:318:11)

Do you mind reporting this issue at GitHub?

It seems the playground needs a few updates after some node classes have been refactored.
