Updated a nodeBB to 1.13, all seems relatively fine, though, I was not paying attention and I updated to v1.13.4-3. - that's ok for now, seems to work.
However the ns-embd plugin is not embedding tweets, just leaving a blank blockquote. Youtube videos embed perfectly fine, so I suspect the watch + replace needs tweaking?
