GR

I contacted Microsoft support, they told me to contact Mojang as they are the developers of the game.

So where do I submit a Minecraft account issue? I thought this was the new Minecraft error reporting website.

You should considering this has nothing to do with a purchase, it is part of the Minecraft Live events.

No this is an issue for you as it is about Minecraft.

Could you by chance check your AI as it clearly cannot detected that my own bug report was in English?

Uh I wrote this in English, it is the only language I can read and write in.

I recently started a project to collect all tropical fish variants and noticed this as well. Black can be found as both base/pattern color. I play Java, version 1.19.4.
Tbh I hope it will become a feature and not a bug, they're very cool fishes.

I see it as an issue with most enchanted items in 23w07a, compared to 1.19.3: enchanted items in the latest snapshot have barely glowing effect, which makes them almost undistinguishable from not enchanted ones.
Compare, in both pics, the items: golden apple, enchanted golden apple, water breathing potion and enchanted leather boots.

I have the same crash, but with "parrot" instead of allay, exactly as another user reported in MC-250350

Happened in our realm as well after update to 1.18.

The dark patch kan partially be restored by placing torches, but it's not fully resolved to normal daylight.

Got the same.

In the world with same seed as of my previous comment, I found a shipwreck completely on land (coord 537/z/-1203), 3 chests, one with buried treasure map: no lag at all.

Lag seem to occur in my world only when chests are located underwater.

I experienced the same in 21w39a (in fact it's quite worsening compared to 21w38a, where there was just a lag), with chests in shipwrecks and underwater ruins. I can't even tell if it depends on the presence of a buried treasure map, because the whole game freezes and then crashes while trying to open the chest. Memory usage goes from ca. 60% to 100% when trying to open the chest. Music is no affected.

In 21w38a there was just a lag, no game crash.

Ampolive: I'm sure I'm in the same chunk (removed a block on very top of chest).

To replicate: seed -1037759586794373933, coord of underwater ruin ca. -900 / z / -490. Singleplayer world. Plain vanilla MC.

I confirm what pine1needle writes for both 1.17.1 and 21w38a.

(edit: seed and coords have all negative sign, I don't know why it gets strikethrough when published)

Thank you Anthony for informative reply and your time.
