I'm just playing the game in a random order, and have only entered the cemetery now. I am an adamant saver/reloader, and save slots 4-10 broke. They now appear blank on the screen, and if I try saving to them, it's responds with an error, and if I try loading from them, it crashes.
*EDIT*
Alright, I managed to get it working. Apparently the game crashed or something and deleted the save folder 5, and thus nothing after that folder was appearing nor loading. Fortunately I only lost about 30 mins worth of playing.
