On Switch version the game starts crashing regularly at most but not all attempts to save (either when a day passes or on a quit to menu), basically making it unplayable after a while. On multiple playthroughs on separate profiles this has started happening both for me and my housemate after about 16 or so days into a cursed world altar, but the issue has persisted even if I intentionally die to leave the altar and return to my main map. For us this began happening during the Death world and the Greed world on our playthroughs respectively. pls fix! it basically bricks the entire save file by making it unplayable.
On the Greed world it started happening during the King's beer quest for me.
