If you add bone meal to small dripleaf stems that are in two block high water, and keep adding bone meal to the highest waterlogged stem, water source blocks will appear in parts of the stem, and will keep appearing when you bone meal the waterlogged stem blocks.
How to Reproduce :
- Put a small dripleaf stem in two-block high water and add bone meal to it.
- Keep adding bone meal to the stem that is right below the surface until a water source block appears on the stem.
- Add bone meal to waterlogged stem blocks on the stem until more appear.
Goat babies do not follow their parents. This happens with both bred and spawn egg goats.
Steps to Reproduce:
- Spawn 2 goats
- Breed the goats
- Watch as the baby goat wanders off and doesn't follow it's parents
Microsoft Windows 10, Java 1.8.0
Goat babies do not follow their parents. This happens with both bred and spawn egg goats.
Steps to Reproduce:
- Spawn 2 goats
- Breed the goats
- Watch as the baby goat wanders off and doesn't follow it's parents
Goat babies do not follow their parents. This happens with both bred and spawn egg goats.
This is inconsistent with other animals that can breed.
What I expected to happen:
Goat babies follow parents
What actually happened:
Goat babies wander off and explore with no parents
Steps to Reproduce:
Spawn 2 goats
- Breed the goats
- Watch as the baby goat wanders off and doesn't follow it's parents
Goat babies do not follow their parents. This happens with both bred and spawn egg goats.
This is inconsistent with
other animals that can breed.What I expected to happen:

Steps to Reproduce:
Spawn 2 goats
- Breed the goats
- Watch as the baby goat wanders off and doesn't follow it's parents
Goat babies do not follow their parents. This happens with both bred and spawn egg goats.
This is inconsistent with sheep, cows, pigs and other similar animals.

When putting glowstone in ore features in the latest snapshot, the glowstone generates, but does not give of light, you must update the glowstone individually. I discovered this while creating a custom dimension. I tried optimizing the world as that is what it said to do for MC-151906, but it only worked once and did not update the lighting after that.

3. Go to the cave dimension by /execute in fsb:cave run tp ~ ~ ~
4. Do /locatebiome fsb:glowstone_cave

I have a worldgen data pack that adds new biomes and dimensions. It worked perfectly in 21w19a but does not work in 21w20a. The game says that the datapack failed to validate.

I can't play with my worldgen data pack on 1.17 Pre-release 4 becausethe game failedto validateit and gave an error. The game did not flag anything wrong with my files, so I have no idea what the problem is to fix it.When my structure feature and template pool files where referencing an invalid structure, the game would fail to validate the pack and gave a Cannot invoke "crn.d()" because the return value of "java.util.function.Supplier.get()" is null error. This is very annoying and is not helpful to data pack makers trying to debug their pack.

When adding my worldgen data pack to the game, the game fails to validate it because of this error: java.util.concurrent.CompletionException: com.google.gson.JsonParseException: Error loading registry data: Missing value [0] : ResourceKey[minecraft:worldgen/configured_structure_feature / minecraft:fossil]
As far as I know, fossils don't have a configured structure feature file. So I do not know how to fix this as it is a Minecraft worldgen error and I have not done anything to affect Minecraft's worldgen.

How to reproduce:*1. Download provided data pack
2. Add it to a new world
3. Notice that the debug log gives an error about fossils.

I now think the game crashed because I left the "structure_starts" in the .json. Which means that the game crashes every time something is wrong with the .json.

I removed the depth and scale, but that crashed, so I copied a biome and added a custom feature to it, and it also crashed, I don't know what is going on.
Ever since 21w37a, support for custom structures with worldgen has been removed. There was no mention of it in the changelog, and no official word on it being removed, that I know of, which leads me to believe this may be a bug.
I have attached two biome json files below, comparing the difference.

Thank you for your report!
However, this issue is Working as Intended.
As Flashbulb pointed out, the biome is named stony_shore.
Please note, that mechanics of the game may change between updates.
Things such as graphics, sounds, world creation, biomes, redstone, villagers, and animals may not work the same in current versions.

MC-225850Your error is most likely coming from the fact that your custom biomes are in the minecraft folder and not in a new folder. This is likely causing the issue because you need to put new worldgen features/biomes in a new folder, and not in the minecraft folder.
WAI. The Nether biomes do not generate overworld ores. Only Overworld biomes generate overworld ores. If you want deepslate ores in the Nether, you have to add them by editing the biome's .json file.

I have attached an image showing the difference between the armor points.
This report is invalid as your game was modified when experiencing this issue.
This is caused by two reasons, the absence of deepslate in the "default_block_nether" tag, and the fact that the nether gold ore and nether quartz ore only generate in netherrack. Ancient debris however generates in the "default_block_nether" tag. This is probably WAI as the ores don't generate in deepslate and only generate in netherrack except ancient debris.
You need Java 16 and not 8 as of 1.17.
Your version is outdated. 1.12.2 is no longer supported on the bug tracker. If you can reproduce on the latest Minecraft version, feel free to do so.
It looks like your game is modified. Spigot is modified server software and is not supported on the bug tracker, if you can reproduce this issue in a vanilla environment, feel free to make a new report.

I accidently left the "depth" and "scale" values in the biome.json. I didn't know it was a problem because the game never gave an error so I assumed it was ok, until I loaded the world.
You have to enable it in your Microsoft settings.
What category did you put bees in? If it is the "ambient" category it is WAI but if it is another then it is probably a bug.
Can confirm, I have had this happen as well with tropical fish.

Invalid because your game is modified. Feel free to create a new report in a vanilla enviroment. Also that is able to happen so it isn't a bug.
This is not a valid parity issue as armour stands were introduced before the Buzzy Bees update.
This project is for Minecraft Java Edition (MC) for Bedrock Edition head here.
I am pretty sure this is WAI as an old growth forest is a real thing. The biomes are not meant to be called just growth forest as it is actually an "old growth forest".
Make sure your are logging into the Microsoft login and not the Mojang login.

I can confirm, also I have not seen a single tropical fish in a lush cave, but they might just be rare.

Try looking in your recycle bin for the deleted world, or try loading a new world to replicate the issue.
Please provide seed and coordinates, and a screenshot with the F3 screen enabled.
Can confirm, but might be intended.

MC-236907, resolved as "Won't Fix".Right now, only the terrain itself is the same. Features such as ores and trees are not similar, which makes this more of a feature request.
Works as intended, glow squids can spawn in any area below Y-30, so a flat world causes glow squids to spawn there, which is also why slimes spawn so frequently in flat worlds.
This is due to the azalea tree not checking if the block below it is a valid base block, unlike other trees, which check if they can be placed by checking if the sapling could be placed there.

Works as intended. Azaleas can spawn in any biome including deserts and badlands.
Structures are currently hardcode into generation, which means that custom dimensions can't have structures. There is currently no way to choose what structures generate in which biome.

That is a stony shore biome. It generates where beaches can generate.

Invalid because your game is modified. Try turning off your mods and see if that works. Also try pressing F1 to get your hotbar and hand back.
Because you are using Optifine, this issue is invalid. If you can reproduce this in a vanilla environment, please make another report.
I have noticed as well, that some entities do not carry over any held items. I have a structure that places skeletons with stone swords, but on generation the swords are bows.
So I would change from just "armour stands" to all entities.
@Michael Wobst I have attached new screenshots with the night vision effect.
This issue is still prevelant in 1.18.2.
I do not know if this is still an issue with 1.18.2, I do not know how to reproduce this bug, and I also gave up on the data pack.
This is an issue caused by OptiFine.
Can confirm.
This also happens very often with custom structures.
This issue is fixed as of 1.19.
Can confirm in 1.19.3
