What happened: The game crashed when I wanted to complete the Master Slime altar by offering the backpack.
I started the day, went to the temple and had the cutscene with the goddess. Then I went to all the guardians to unlock their altars. I went to my farm, BOS, and the monkey shop to gather the things I could already give, then went back to the Mural to offer them. The backpack was the last thing I gave, the screen froze and the game crashed/stopped.
I only tried this once, didn't want to have to restart again, but I've been told in the chat that others have already talked about it and I saw other reports here.
Platform: This happened on xBox series X (the reason I reported this because the other reports have only been for steam)
Game Version: v1.1b-1237
I don't have a video of it since it happened surprisingly.
