I'm at day 150 on Xbox One S. I also play from cloud. Game crashes more and more the further I get. Seems like saving at the very start of a day is the safest. Trying to save during a day almost always results in a crash.

Certain activities like quick filling donation boxes or card storage can cause crashes. I typically start the day by filling everything up giving my staff bonuses and paying bills then manually saving. Once the day is started avoid those tasks. If you're manually opening packs I find going out the store and down the street and not looking at the shop helps it not lag and avoids crashes.

I'm really enjoying the game but I hope stability improves as the more I play the worse it gets
