Hello there, I'm the guy who made these files XD Each month, I prepare some save files for Spedumon, which he then puts into the game folder. Why? Because the game was made in RPGMaker, and that program really doesn't like loading older save files into newer game versions with new scripts and stuff. There have been plenty of bug reports in the past, and the problem usually was that someone used an older save file. That's why I started preparing premade save files that always put the player with decently leveled characters and lots of gold/items right where the new content is. Nowadays these problems have gotten a lot rarer, but they can still possibly occur. As for why your own save files disappeared, the problem is that, unlike other programs, RPGMaker saves it's games within the actual game folders. Which means, when you download a newer version, it also replaces the save folder. Check the game, then the www-folder inside, and copy the save-folder somewhere else, if you wanna keep your save files next time.
