Critical hit particles can be black if inside a block
The Bug
Found while testing MC-271391 in 24w18a, however, this issue is likely to have existed before.
When you critical-hit a mob while it is in a small area surrounded by solid blocks, some critical-hit particles will appear black (like suffocating mobs).
Refer to the video attached.
How to Reproduce
Refer to the image attached.
- Make a box that is 3x3 in size and two blocks tall. Do not use transparent blocks like glass. Dig out the middle so that you are left with an outline of blocks surrounding a 1x1 area.
- Summon a mob inside of it, like a creeper.
- Critical-hit the mob by jumping and then landing a hit on it while falling (preferably without a weapon).
- Note how some critical-hit particles show up as black.

The Bug
Edit: Please report this bug as Invalid as I accidentally had doMobLoot as false. I am very sorry for the inconvenience.
Ever since snapshot 24w18a, mobs killed do not drop any experience or their usual drops at all.
See the videos attached. I do not have any datapacks installed, and both are vanilla unmodified instances.
How to Reproduce
In 1.20.6, spawn a mob that drops something commonly (like a cow), and kill it. Note how it drops experience and sometimes drops its usual drops.In snapshot 24w18a, spawn a mob again as before and kill it. Note how it does not drop any experience or drops, no matter how many times you try.
Additional Notes
In the videos, I killed the mobs with my fist. This is because I thought that only then would mobs not drop anything. However, they do not drop anything even when killed with a weapon.
I have the Strength effect in the videos to allow me to quickly kill the mobs. However, I have confirmed that mobs still drop nothing, even without Strength.
The Bug
Potion particles from a mob/player can turn dark if inside a block, like suffocating mobs. It would be expected that these particles were normal-colored, or not show at all.
How to Reproduce
- Make a small 1x2 hole in the ground. Make sure the blocks surrounding the hole are full solid blocks (not transparent blocks like glass).
- Summon a mob inside it using the /summon command or a spawn egg, like a creeper.
- Give the mob an effect using a splash potion or the /effect command (if using the latter, make sure to set hideParticles to false).
- Note how some particles that go inside the blocks turn black.

Can confirm.
Thank you for your report!
After consideration, the issue is being closed as Won't Fix.
Please note that this is not the same as Working as Intended, as this bug report correctly describes behavior in the game that might not be the intended or desirable behavior, but it will not be fixed right now. Sometimes, this is because the issue reported is minor and/or impossible to change without large architectural changes to the code base.
