After installing Windows 10 updates or even when there is no updates to install, my character save or whole game resets back, this includes opening the program and having to select languages and adjust brightness again, this happens after I take a break from playing or opening the program for a few days (1 or more days of not checking back to the game basically). 

Since the character save is stored locally in cache - I'm not sure and don't think that it's my antivirus causing this either since I double checked on what they classify as system junk or program cache and I don't see MCD's save file location there (%localappdata%\Packages\Microsoft.Lovika_8wekyb3d8bbwe\LocalCache\Local\Dungeons)
So I'm assuming it's something else. 

I hear this also happens to people who's power cuts off mid-game or had an error occur in which they weren't able to go back to camp or close the game properly.
