Ok so here goes for those like me who came looking for a full save but just found a semi-full save.
Same as the other one:
1. Place in: C:\Users\[User]\AppData\Local\VampireMansion\Saved\SaveGames
2. Set to Read Only in file properties.
3. Run the game and play any mode [Velina's Room should work if you run the slot machine]
4. While game is playing change file properties and remove read only
5. Exit game to desktop and re-enter to verify if save was succesfully added.
In case it wasn't try again, but after doing step 4 run one of the hunting games in Velina's room and get some points before loosing, this is to force a save game update.
PS if you run into issues with steam cloud saves you can try placing the save in:
C:\Program Files (x86)\Steam\userdata\[Numbers Here]\2280520\remote
This is a full save with all outfits, endings, and room stuff bought. for the version updated on April 26, 2024
