game wont load

One of my sims saves won't load through. I have tried removing mods. I also tried deleting cache files and the local thumbnail file. Deleting the game. Repairing. My other saves work just fine and so does this one if I go back to an older save in the game, but once I save it again, it says error. (This is also a save file from another creator, which I'm unsure matters or not).
