Title tournaments were special - Look at my profile page, I was lucky to get all kinds of special trophies, old and new. However, if you do a little search, you’ll find they were officially discontinued and the feature request to continue them has been declined.
Also, the Oza Treizes title was created after that (by me), so it’s even less official. One thing that could/should be fixed is, when you hover the mouse over the 13x13 tournament trophies, you should be able to see the names of the tournaments as those for 19x19 and 9x9 tourneys, instead of “gold/silver/bronze_tourn_13”.
As the TD for manually-held title tournaments after the official ones stopped, I do still consider them ‘official’ myself. Therefore, I might start creating pages for them on Sensei’s Library. Besides that, if you’d like, I can send you the link to the badge that you can paste in your profile page (as what Nova League did).
