I play on the most recent version for Minecraft bedrock PS4. I have a guardian farm where pistons repeatedly push tridents into guardians and kill them, so I get the drops and XP. However, usually after around 5 minutes of running the farm, the world crashes. Sometimes the crash happens much sooner than that, and it is infuriating. I know there is a rare bug in the game where killing a guardian crashes the game, and it's just infuriating that it still hasn't been fixed.
