Game keeps crashing, progress disappears

My game has been crashing constantly since the last update, and every time I resume play, I lose any progress I had made in the last few hours. 

The latest crash has reset my game back more than a full day. I’ve lost Simcash, sweet treat rewards, Llamazoom tickets, purchased items, thousands of simoleons, as well as a lot of progress in different stories. 

Absolutely fed up with losing my game progress and rewards, and having to restart tasks, but this latest crash takes the cake. 

How is it even possible that I lose over a day’s worth of progress and all those rewards?!
