Alaric's research on the stemma of Nikulás saga leikara that used to live on this webpage has now been integrated into the working paper at https://docs.google.com/document/d/16bfuiyy0WCaDyrmeN50e3iDnr0Pa9AAMbp1OJHrTUXM/edit?usp=sharing. If you're desperate to check earlier versions of this page, the Waybackmachine should see you right: https://web.archive.org/web/2021*/https://alarichall.org.uk/nikulas_saga_stemma_article/. Have fun!
