When saving and exiting my world, there is a chance that the game crashes. This doesn't happen all the time however, and noticed that it's more likely to crash when playing in the same world for a long time period. This problem is annoying since usually when I get back in my world, I noticed that my animals (horses, llamas, foxes, sheep, etc.), villagers, and iron golems randomly despawn. I would be grateful and happy if this problem gets resolved since it gets kind of tiring in trying to replace any passive/neutral mobs that despawn, and trying to rebuild anything that got rolled back after the game crashes (although it's not a lot to rebuild, thank goodness for autosaving 😛) If you come across this bug, please vote on it, and thank you for taking your time in reading this bug report.
