After updating to 1.17.10, not a single mob have dropped any loot or any experience, even with Looting 3 sword.

I hope this will get fixed soon, because this bug is exteremely game-changing.

I am playing in my own solo world on Windows 10, Minecraft Bedrock stable version 1.17.10.

Edit: This isn't and never was a bug. The "Mob loot" option in my world settings was disabled for some reason and hence the issue. False alarm!
