Game stuck on black screen with saving... Won't update

[fernweh21]

I was playing in Deep Woods and at the end of the day when I saved, the screen just stayed on the black screen with saving... at the bottom and won't update to the next day. Is there a way to save the game without losing my progress. Here is the smapi log. Thanks for any help in advance.

[SongOfTheSky]

I'm having the exact same problem, with a pretty similar (if not exactly the same) smapi log. Only happened once i started changing the wallpapers, flooring, and furniture in my farmhouse. I am using custom wallpaper, flooring, and furniture mods, so I am thinking maybe one of these mods messed with the game somehow maybe? I have no idea how to fix this, and dont know for sure that that is what is causing this. Can anyone help us both?
