I noticed all my animals disappeared, I also couldn’t open any of my chests or even my own inventory so I tried to save & quit the game. However I’ve now been stuck on the Saving world screen for 15 mins. The little arrow is still bouncing above the chest but it’s been stuck like this for a while. I haven’t turned my PS4 off… I don’t want to lose my world or any of the progress I’ve made. We installed Minecraft version 2.31 just a few days ago.
