This is my only problem now. Please fix this so I dont have to start a new game for no good reason

Ok I have solved the crash problem for my fourth character causing the game to crash as battle starts by simply saving the game and that fixes that and also saving on my completed file reminded the game that it was beaten and the music player and soul of rebirth were where they belong. But now I have no fourth character. My final party is just Firion Maria and Guy. Leon and any fourth character do not exist except for their dialogue in cutscenes. They dont appear but you do see what theyre saying but thats it. When I tried soul of rebirth it started out with Minwu as always but when he walked south to find Scott his Sprite changed to a shadowy version of the light emperors Sprite. Scott is the only one who you can have in your party in soul of rebirth and the other 3 just dont show up in the menu or battle. Just when they join thats the only time you can see them. Im almost positive this all occurred because all data prior to this update is completely obsolete. I would appreciate an update that would restore my fourth characters so that they actually exist and soul of rebirth can actually be played. I made Ricard so powerful before he died to the point where he can fight the light emperor head on singlehandedly and but now it means nothing if he doesnt exist. Please if theres anything else you can do then just restore them. I dont want to erase what I worked so hard for last week with all the crashing.
