OK, so this needs to be prefaced by me saying that I have not played any previous builds of this game. I had no old save files to transfer to a newer build or anything. So with that out of the way, when I have run 1.2.03, it has functioned perfectly well except for two things. (1) When I try to manually create a save file, the game will not let me do so. It doesn't seem to recognize what I'm trying to do and simply doesn't allow me to save, even though I can get to the function and even see empty save files available. (2) When I try to disable the autosave function (which may or may not be screwing up the save function, but definitely hasn't worked since when I've gone back to the main title the game itself hasn't even autosaved) the game crashes as a whole.
I don't know if this problem is exclusive for people who have only played and downloaded this current build, but I thought that you should know about it, Siren. Hope this helps and let me know if something gets fixed.
