Details of your issue: Game crashes on end-of-day save. This happens whether I go to bed, fall asleep in the house/Ginger Island house, fall asleep in the farm or fall asleep off the farm (including Ginger Island). It does not happen consistently. Sometimes I play several days in a row, then it crashes. I have had the same day crash multiple times before I get a successful end of day save. Sometimes when it crashes, there is a mid-day save that I can start, and sometimes I have to re-start at the beginning of the day.
When the game crashes, it just repeats the "Saving..." over and over again. When it works, the save completes at the 3rd or 4th repetition of the "...". When it crashes, I've waited up to 20 minutes without the save completing. I have to quit the game, and then restart.
Screenshots/video: (highly encouraged)
On the day of your issue, did you load your game through the Load Game menu (you wake up in the bed)? Or was it an "emergency load" (i.e. one where you start mid-day wherever you left off)? Both.
Any other info that might be relevant: (additional details that maybe don't fit in the main issue or something you think might be related). The save I play, where this happened, is on Year 31, and began on version 1.3. I have a lot going on, with kegs on most of the game tiles, a full farm of Ancient Fruit, and a full basement of Kegs. One of the worst days was where I was harvesting Iridium Starfruit Wine from the Kegs in the basement. I had to play the day three times, doing less each time until it saved. The only thing that seems to help is to do less during the day, until I get a successful save. I started 1.5.6.39 during Winter. The crashes have happened during Winter and Spring, which is as far as I've gotten so far.
