I don't remember why I credited Abby Howard specifically, but Lonely was released before the full version of StP was released, so presumably I was going off the credits which were listed in the demo, or because I originally found the demo fo StP from Abby's Twitter/social media specifically.
In any case, Lonely has been translated into multiple languages at this point, and if I were to edit the author's notes in English I would also need to get the notes re-translated about 7 different times, which isn't feasible.
