”A feature of Minecraft, whether a bug or an intentional feature, that could be acquired in specific versions of the game, and the ability to acquire said feature was, at some point, removed”

~the Minecraft Discontinued Features Wiki

This page is all about things that are now no longer obtainable (e.g. petrified oak slabs) or rare (blank maps for example). Some features have also been removed throughout the numerous updates, such as invalid data value leaves (usually known as "alpha leaves").

Please include the following info

• Version range (if uncertain, give the version it was obtained / removed)
• Owners (players who posses it / had possessed it)
• Info
• Images

Blocks

Snowy Grass Block

The thermal paste block.

A snowy grass block without the snow layer, leaving behind the base taxture of the top part of a grass block. This bug could occurre by either an enderman picking up a grass block that had snow on it and placing it back down (patched in 1.16.x) or by world generation (similar to floating vegetation) (patched in 1.17.x).

Although this blockstate is rather stable (placing or breaking blocks does not cause any updates) snowfall will update the block and a snowlayer will form on it. Al it takes to prevent this is to place a block 2 blocks above the grass block (as shown in the screenshot).

Moving Piston / Block 36

• Version range Beta 1.7 - 1.16.5
• Owners Barrier Town featured some of these blocks.
• Info Moving piston blocks were able to be made when blowing up the block entity of an extending piston in the same tick that the piston extends. This was possible by blowing up a brewing stand with an end crystal and extending a piston at the right time.

This newly created block, that normally is meant to only exist for a very short period, has some interesting properties:

1. Gravity blocks will fall through it when they are falling. They will stay as a falling entity when there is a block underneath it that normally breaks falling blocks, like a fence for example.
2. Gravity blocks can sit on top of it when they are directly placed on it.
3. Fluids don't go through a moving piston block nor can blocks be places in it.
4. Block 36 can support item frames.
5. Moving piston blocks can still be made by using the world border, the block itself can be found outside and a server sided hitbox is projected on the inside of the border (image needed).

• 

  Sand will stay as a falling entity forever when falling through a moving piston block.

• 

  Fluids will stay stationary seemingly stationary.

• 

  Gravity blocks will float on a block 36.

Items

Blank Map

Blank maps are maps that show no terrain, when placed on item frames they will become transparent and make the item frame larger. There are 2 types of blank maps: ones that have NBT data and ones that don't, they can be distinguished from eachother by either enabling advanced tooltips or by some small visual differences when held.

Owner(s): oakmarten (both)

(example of the other type is still needed)

Tall Grass / Large Fern (item)

Tall grass and large ferns as items are only obtainable in village chests (1.14+). Tall grass has a 45.9% chance of generating in a savanna village and large fern has a 18.6% chance in a taiga village.

Mobs

NoAI Ender Dragon

• 

  The dragon is being resummoned after the blocks were placed to block the dragon's path finding.

• 

  The first dragon is succesfully frozen and can be moved.

• 

  Moving the dragon.

• 

  Boats with players can sit on the extremely large hitbox of the dragon.

More screenshots needed

By blocking specific locations with blocks the enderdragon will no longer be able to pathfind it, this results in a frozen dragon. When the dragon is frozen you can push it outside the main end island with a flying mashine. When there is no ender dragon at end spawn during and the dragon battle isn't finished the server will spawn a brand new dragon which will freeze aswell. This allows multiple dragons in 1 world.

A video that ostrich1414 made about the broken dragons event: https://youtu.be/Itqe5GtNs5g?feature=shared

• 

  Oakmarten attempting to use the dragon to clear parts of the lava casts around spawn.

• 

  3 dragons were succesfully moved outside the main end island.

Oakmarten would later also try to clear lavacasts with a dragon and get more than the initial 2 dragons. He succeeded in getting 3 dragons in one place.
