Viewing post in Lost my saves?
I managed to figure out a way around the issue that iyfck was having, as I suffered a similar issue with the Moaning Mod. Uninstalled it and Melon while seeing if I could fix the issue.
After opening the save folder and looking through the saves in Notepad++, all the data was still there in the .mdrgslot(s), but the save.mdrg data was wiped. I then created a copy of the folder to not lose the original data and worked to fix it. I started a new game and sped through the intro, and once able to, created a new save game in slot 1. Exiting to main menu afterwards, I looked into the new M1.mdrgslot data and as expected it was overwritten to empty values expected of a new game, but crucially save.mdrg was now populated with values pointing to the M1 slot. Changing out the data saved in the M1.mdrgslot to the data that I copied from the previous M1.mdrfslot data in Notepad++ and loading the slot again properly loaded all the previous data.
It's a bit of a hassle to do, but it's definitely recoverable. No clue why the game decided to wipe save.mdrg though, might be something to do with the mod or some other thing.
