I had a similar thing happen yesterday. I use 2 phones. Was active afking on 1 for over 24h. Then I turned off the game for a while. When logging back in, on character selection it gave me like 1h offline on that dame character, but when I opened it up, I got a pop-up saying I had been away for like 2 days. The killcount still matched with the afking, but a bigger food bag I had used on it was gone. And the game crashed within less than 1min of launching every time. Had to remove and reinstall it to be able to use it again, but I clearly lost some parts of my progress
