Why don't you just tell/share what you're using to decode saves so people can fix it themselves?
The reason that isn't happening is that people had access to the debug tool after version 0.83 of Man of the House. It was meant for us to fix bugs on the go, before you accessed it in big red letters do not use this unless you have been specifically told to by one of the dev team.
You know what people went in and played and then wondered why this wouldn't trigger or that wouldn't trigger. Have you used the debug console? No. Look at the save, sorry you accessed it 20 times one guy we stopped counting after a thousand we even awarded him a trophy.
This was one of the main reasons the Man of the House thread is so large, because of people breaking their saves and us fixing them, if we could as some were just completely broken.
As for the reason the saves are encrypted as above, this scene won't work, look at the save all the girl's stats are maxed because they edited their saves and are only two game days into the game.
So as the saying goes been there done that got the T-shirt.
So Faerin decided with this game limited access to the debug console and encrypted save to save us a bit of work.
They should be smart and do a backup and not mess with stuff they don't understand. Is manually fixing saves for responsible players less work than chiding a few people who think they know what they're doing?
As for that, you may well be a responsible player, but you are in the minority.
If you put 10 people in a room with a big red button marked "Do not Press* more than half would press it, put them in the same room with the promise of fap material behind pressing the button but you have to wait for 24 hrs or complete a task then you press the button, pretty sure that number would rise to over 80% who just pressed the button.
Hope that answers you query
