Well, the save files are there now. But still, the problem remains... This is kinda hard to explain, but eventually after some time (can be 10 mins or 2 hours) of not playing, when i open the game again, the save is not the latest i made, but it goes back to the second last save i made - like it's using some backup saves. So i have to wait (again it could be 10 min or 2 hours), that the game refreshes those files to the latest.
It's easier to expain on the screenshots. I played the game in the morning, saved it and took a screenshot (latest save is 22/8/19). Then after cca. 3 hours i decided to play again and i opened the game and the saves were 1 month older (25/7/19). The only thing i could do, is close the game and wait a couple of minutes or hours and the save files will change to the latest date automatically.
I don't know, maybe it's my phone or something... But the exact this was happening with FMM 2018.
