The issue:
{NoAI:1}
When an entity has its head inside farmland and the farmland turns into dirt, the entity will be instantly (in less than 1 game tick) teleported above the dirt.
The teleportation works also with entities with NBT
; they get teleported up too.How to reproduce:
[e.g. Floor is at y=10]
1. Place a farmland 1 block above the floor. (e.g. x=10, y=12, z=20) [2017-08-28_11.41.47.png]
2. Summon an armor stand on the floor with the head inside the farmland (e.g. x=10, y=11, z=20) [2017-08-28_11.42.23.png]
3. Jump/place a block above the farmland to turn it into dirt. [2017-08-28_11.42.36.png]
4. The armorstand instantly teleported up.Testing results:
- We can teleport an entity with farmland infinite times a tick, but due to the fact that entities can't go through more than a subchunk every gametick, the maximum (upwards) speed is 320m/s.
- Farmland can be transformed by using pistons to move blocks above it, or by moving it below a block, and the bug still works.
- It is possible to build a survival vanilla friendly 320m/s elevator (a subchunk per gametick), moving farmland below signs in the right order.
- Items can be teleported by placing farmland above other farmand using the right update order (this also works at a subchunk per gametick).
- Endermans (3 block high mob) gets teleported using a farmland every third block.
Why it happens (my thoughts):
I think it's a bugfix ended up badly: they tried to fix MC-104259 and they failed.By the way, it only works with farmland and not with path blocks.
I made a video about to show the bug and to show the testing, HERE (turn on english subtitles).The issue:

[e.g. Floor is at y=10]
1. Place a farmland 1 block above the floor. (e.g. x=10, y=12, z=20) [2017-08-28_11.41.47.png]
2. Summon an armor stand on the floor with the head inside the farmland (e.g. x=10, y=11, z=20) [2017-08-28_11.42.23.png]
3. Jump/place a block above the farmland to turn it into dirt. [2017-08-28_11.42.36.png]
4. The armorstand instantly teleported up.Testing results:
- We can teleport an entity with farmland infinite times a tick, but due to the fact that entities can't go through more than a subchunk every gametick, the maximum (upwards) speed is 320m/s.
- Farmland can be transformed by using pistons to move blocks above it, or by moving it below a block, and the bug still works.
- It is possible to build a survival vanilla friendly 320m/s elevator (a subchunk per gametick), moving farmland below signs in the right order.
- Items can be teleported by placing farmland above other farmand using the right update order (this also works at a subchunk per gametick).
- Endermans (3 block high mob) gets teleported using a farmland every third block.
Why it happens (my thoughts):
I think it's a bugfix ended up badly: they tried to fix MC-104259 and they failed.By the way, it only works with farmland and not with path blocks.
I made a video about to show the bug and to show the testing, HERE (turn on english subtitles).
The issue:
When an entity has its head inside farmland and the farmland turns into dirt, the entity will be instantly (in less than 1 game tick) teleported above the dirt.
The teleportation works also with entities with NBT NoAI:1. They get teleported up too.How to reproduce:

@Derrick Lambert
I can confirm this issue
It happens on servers too. On a big survival multiplayer whitelisted server all the observers got stuck and we had to replace them with "/fill"
P.S. The server was 1.12 vanilla Minecraft (without plugins or mods).
@Conrad Herman
I used two "/fill"s for every possible orientation of the observer (north, south, west, east, up, down).
The first one replaces every observer facing in a certain direction (e.g. North) with a dummy block (e.g. Bedrock, that is not part of the volume selected).
The second one replaces the dummy block (in this case Bedrock) with the observer in the chosen direction (in this case North).
Example:
1) /fill x y z x1 y1 z1 bedrock 0 replace observer facing=north
2) /fill x y z x1 y1 z1 observer facing=north replace bedrock
You have to do the same thing for every direction (6 times).
Remember to use "strange" dummy blocks (like structure_void) to be sure not to replace other blocks.
Works in 1.12.
A thing I noticed while using MCEdit is that the stuck-buggy observer becomes a non-recognized block: this means that it has invalid tags.
I think it doesn't get updated because of that.
Now it seems to be fixed.
