Not working in Sketch Version 62 (91390)

[shornuk]

Is this still maintained? I've used this is the past and it's been great but I'm having issues when trying to use it in Version 62 (91390)
On an empty document with just a few artboards, it says it passes validation, (😍Looks good!) but when I run Validate and Clean nothing happens.

In another doc, it fails validation with a message "Invalid artboard name" for some of my symbols.
