Solved!!! Hello, This is my log file: https://log.smapi.io/155e49ca134440f48dd6c9a6bbf40f6b I've searched for answers with other people who are having this problem but the bug doesn't seem to be the same/the fixes don't work. I just updated both SMAPI and the game, and all the mods I have which have new versions. The error is in only one of my save files, all the others work fine. The crash happens when the game tries to save and go to the next day, maybe because of the new jojo mart cut scene? I deleted Paritee's better animals mod from the game, but this is the only file where I had special animals, I don't know if that is affecting the save file? This is my absolute favourite save file and I'd be gutted to lose it - if anyone can help I'd be incredibly grateful!
