Hmm, could be. Those links also need to be relative to the current file, so they could be broken links as well. Deepdwn won’t give you a 404 page for that, they just won’t open.
If autocomplete worked to generate the link, I’d expect that control-clicking it should take you to that file. If not, that may be a bug that needs to be investigated further.
