I used a save from version 0.20a in the latest version of the game and there were no problems at all like game crashes and others. True, for this I had to disable the "savefile" script, otherwise the inscription on the screen "obsolete" and the game did not continue. So the cause of the problem is not saves. The game files are packed in the rgss3a archive, i think that just need to unpack it into the game folder (for this you can use a decryptor if you do not have RPG Maker installed). I always do this with RPG games and there are no errors or game crashes
Thank you, i managed to download and use a decryptor to extract the files and i did what you suggested, but even in this last version there's no such file named BUST_MC_BODY_CLOTHED_1 lol. How is that possible? Maybe it's an error like the other guy here said, about unziping error. I will download again, use the save, extract the files and see if this file is there again.
EDIT: Turns out i just had to download the game again

and i'm using the old save, so everything is working well so far. Thank you guys.
