The question is not that you hurt me with this. The question is in the sentence. The first thing we think about when updating is whether we will be able to use the old save. Without any suggestions, we know about it.
It is profitable for us, and we think about the benefits, believe me. And if there is no such opportunity, it is not because we are harmful.
And if you had originally asked politely why you can't use the old save, I would have politely explained why.
Directory: ToML/game/saves if there's no save folder, you need to create it.
I realize the language barrier here, so let me first insure you that I am polite
There was no need to ask why an old save might not work, because I do read the full OP before playing anything.
It's not the first Ren'Py I've played, so I know there is a save root folder hidden in the AppData somewhere, where all game saves have a "back up", this is usually a great thing so we don't need to copy/paste save folders from older versions to a new one, but the not so great thing is if bugs etc. create some kind of corrupted root save file, causing grief for the player as well as the developer when questions about it starts pouring in.
So basically the best way to make use of the provided saves, would be to do so in a "clean game", without any old saves.
To do so, one would have to first locate the AppData saves for your game, delete them, download/install and start up your game. Close it, download the provided saves, copy the save folder into that directory: ToML/game
and now only the provided saves from the OP should be in the game, starting up and playing would automatically create a fresh root save in the hidden AppData.
To not worry about the AppData and just place the provided save files into the games save folder, might not create any problems at all, but if it does then you'll receive a whole lot of gray error copies from players. Was trying to spare you that.
Now that was only about the first part of my original post, you didn't comment to any other of it's content, so I'd have to assume the first part removed your will to read the other parts and that's fine, I don't want to waste your or my time any further, have a pleasant day and best of luck with your game
