I can provide a save now as it's happened again. I have a habit of accidentally saving over files that would benefit you. I'm not sure how to provide it however, as I can't simply upload it to itch.
How would you prefer to receive it?
My best assumption on how it happens is something to do with beginning Desmond's 3 day wait period, or perhaps even the fact that I've made a conscious decision to not take back the luck book from the maid. Afaik it's useless beyond access to Arwin's study so lately I've had a habit of letting her keep it lol. These are the only two events I think my recall blocks have in common, off the top of my head.
