I'm on it!
I'll see about incorporating this extra code for reversing time.
In these sandbox/freeroam games, it's usually difficult to go further back than the morning (on that day) without risking breaking something. This is mainly due to the fact that the transition to a new day usually has code to move
I don't think Maid Lain has expressed (at least in public) a decision to retire, though. She just suddenly stopped posting/appearing shortly after her last mod release for Mythic Manor in mid March. Both her Patreon and SubscribeStar pages are still open, with no posts since that release.
However, in the last six months or so, we've also "lost" LaikDink (retired), AB (retired), RiamMar (retired), and Sancho1969 (lost, inactive since late June), to mention a few, so some of us other modders have chosen to take up where they left off, either continuing with their existing code, or reworking the mods from scratch.
