..? have you tried the "Unsaved stat boosts fix" and "Death-defying stat boosts fix"?
i'm not quite sure which bug(s) you're referring to based off of one sentence, but it sounds like it could be up those patches' alleys.
I was on a deadline, so I was more concerned with getting other things done. I already did close off the abuses anyway, so they wouldn't be a problem, and I wouldn't want to carelessly mess with save-related things until I was at a reasonable stage for possible backtracking given my reliance on Hex Workshop and Ghidra.
I've been more focused on both trying to advertise the patch around, unfortunately to limited effect with how practically languid the game's community is; and focusing on my new video series, which is a No Damage/Effective Minimalist Run of Zelda: A Link to the Past. (Oh, and by the way, since you're here, I did mention you in my latest video because of your Monster Stats FAQ making clear that most Dark World bosses can't be damaged by the L1 Sword's regular attack, something I found when looking for anything that could have forced getting the Master(/Tempered) Sword even with the Death Mountain Descent.) I would want to revisit the patch more actively at some point down the road, though, but I'd have to figure out how the Checksum is handled before doing anything further because I suspect it is used in the middle of gameplay in some fashion that set off a bug that I had ran across.
I'd be up for talking if reasonable in the interest of coordination. My interest was in getting something presentable released. That doesn't mean it's complete. I couldn't even remember everything that was missing. I wouldn't mind aid in addressing key issues as long as it doesn't get too pushy.
