Crashing every few hours

Every few hours my game starts crashing. I moved a teen Sim out of the parental home into their own tiny home and since then there have been constant crashes. Sometimes when I'm in build mode, sometimes when she's arriving home from work, the most recent was when I had restocking a table for her yard sale. 

I don't use mods, I've checked my graphics for updates, I stopped loading in dx 11 because I thought it was the issue. It went from multiple times an hour to once in about 3 hours. My issue is its only this one Sim. If I play her father and sister's household it doesn't crash.
