Importing sub flows. Something isn't working

In reference to this thread:

My last post.

Ok, you may need to look towards the top.

I posted a subflow.

I stuffed up, and wanted to go back to the working version I posted.

I copy/paste/import it to NR.

None of the internal links exist.

The links to/from the output/input are there. But no internal links.

ARGH!

This shouldn't happen - yeah?
