#sims 3 problems

After 10 generations, multiple moves, and a very robust story progression, my legacy save is well and truly fubar. When I sent Dylan to Egypt, I got the same vendor notification over and over. In France, I saw the exact same NPC sim twice. The game is lagging, even after merging cc and resetting the town, which it normally does not do. It takes Dylan at least 30 sim minutes to change clothes, go to work, get in the shower, or go to bed. And sometimes the sims have a weird melted look before fully rendering.

I've tried googling some performance tricks, but think the save is too broken to fix. The most painful part, really, is that I will likely have to sacrifice all the keepsakes. I'm especially sad to lose nine generations of family photos and all the bottles of nectar that have been aging since Noelle's generation.

UPDATE: I put everything in Dylan's personal inventory before saving him to the library, so the only family heirlooms that were lost were a couple of festival photos, which I don't mind losing.

I've managed to save the Malan Hall dormies to the library, along with my current Dylan, so they can still be friends in a fresh save. I'm not bringing his siblings, so we'll just have to imagine them happy and thriving in Isla Paradiso. And even though Sims 3 mermaids aren't immortal, we're going to pretend they are, so Mara and Mason will live happily forever, together under the sea.

It's also likely that the apartment renovation storyline will fall to the wayside because the routing in St. Claire is kind of a nightmare, and I'm kind of in love with this house by @theplumdot which sits on the lot where Keahi lived in Sunlit Tides. I feel like it's kind of a full circle for the legacy for Dylan to live there with (HOPEFULLY, DYLAN) Zoya and their family since that's where Nara was born.

UPDATE: I realized that if I move them to Sunlit Tides, I will have to annihilate the entire population and let SP repopulate because there are so many people who have appeared in earlier generations. So, I'm trying a fresh St. Claire.

Well this happened...

I have no idea what to do. It’s not cc or mods because all my other games with the same cc run fine and have never gone bad. I don’t think it’s the sims themselves bc I play them as households and they work fine.

until THIS comes along:

Also me:

SO I have been merging CC and adding things into my game and I think I have a piece of broken/glitchy baby cc that causes this when I zoom out and/or rotate the camera around and this is the only picture I have been able to get and its only from the baby. Any one else ever experience
