One Save keeps crashing

One of my legacy saves keeps crashing. A few months ago I did think it was maybe corrupted (which made me very upset and I lost my motivation to play,) but I just picked the game back up moved all my sims and items into a new save. But it still keeps crashing? My other saves are fine as far as I can tell, new saves with new sims are also fine. Can you corrupt a save through importing tray files? I'm usually pretty good at figuring out bugs, but this has me pretty stumped.
