All post-Gen 5 avatars have now been indexed on AvatarDex.io You can find them under "Artist Releases" tab Fun fact, there have been 148 of these releases so far, bringing the total of unique artist-created avatars to 1,067 across all Gens

@vander_dev I counted 177 including two test mints this month, 30 of which haven't released yet. That's a difference of 3 avatars I'm apparently lacking and it's hecking killing me now
