Sims 4 Keeps Crashing When Saving

A few days ago I was playing the Sims 4, and I had one of my sims visit some NPC's house. She was making enemies because she's evil, but when she tried to go home, it crashed. I reloaded, got her back her enemies, and saved while still at the NPC's house. When I tried to go back home, though, it just crashed again. When I reloaded, I started off with my other sims back at their house, and waited for the other sim to go to work. When she got back home, I tried to save, and it crashed. Now whenever I try to save, no matter where I am, it crashes. Even if I'm on a different sim family it will crash when I attempt to save it.

Please send help.
