Crash after selling kittens

My game crashes after I try to sell a kitten. As soon as the adoption agency arrives the game crashes. Ive had to redo this same day multiple times before I started saving every in game hour. Of the two hours I've spent playing today, I haven't gotten through one full day. I tried debugging the kitten, but it still crashes. Its also not just this specific kitten, before I started saving every hour when I'd have to redo the entire game, my cat would give birth to a kitten, it would crash when I try to sell it, the cat would give birth to a different kitten and the process repeats itself. Im incredibly annoyed cause this was the only free time I got this week.
