When loading a save the game crashes

I have 3 packs installed on the sims, 'Highschool Years', 'Cottage Living', and 'Dogs and Cats ('My First Pet' included)', no shaders, and a decent, but not game crashing amount of cc. When I try to load up a specific save file the game crashes, this save file is on a cottage living plot where the Watson family lives.

The day I was playing the save file it was glitching a lot, the teens didn't do their homework, and I tried to sign one of them up for an afterschool program in the 'Highschool Years' pack, but that wasn't working either, I tried resetting the sims but nothing worked, so I saved where I was at then I closed the game hoping something would happen, after about an hour or so I wanted to try and see if it would work, but now I can't open the save file at all, and my game crashes.
