Using clone with the move parameter at the end on a door yields in the bottom half of the door to be moved, and the top half to jump to the west side of the block it is in.
Reproducing:
- Place a door down (material doesn't matter)
- Place a command block down from 2 blocks from it.
- Type the clone command in the command block, so that the door gets moved away from it's original position (does not matter how far)
- Execute the command block
EDIT: Same applies for pistons (without the upper part snapping to a side of course), and tall grass. I also associate it with a crash, for which I am creating another report.

Clone moving doors only moves haflf of them
Clone moving doors only moves half of them/clone moving doors only moves half of them
I was testing for more bugs for issue
MC-61170( https://bugs.mojang.com/browse/MC-61170 ), when this happened. I have not been able to reproduce it since.EDIT: If it makes any difference, the grass was "powered" by a piece of redstone dust.
Using /clone with the move parameter at the end on a powered rail, detector rail, or activator rail that is next to any redstone device except pistons will activate said device.
Reproducing:
- Place blocks down like on the screenshot
- Type the clone command so that the rail gets moved away from it's original position
- Execute the command block
If Iwalk on a walkway ofcomparators with grass beneath it, I hear the grass's sounds. It's like the sound engine ignores thecomparators.When walkin on a walkway of some thin blocks with a block beneath it, it sound like I'm walking on the block below. It's like the sound engine ignores the thin block.
Blocks affected:
- Carpets
- Rails
- Pressure plates (besides clicking, it still plays the walking sound from the block below)

I also confirm this to happen with fill and setblock clocks.
I have just discovered this myself, and I wouldn't call it a bug.
It is probably not related to the issue mentioned, because we aren't talking about the position, but the way they render.
If I'm not mistaken, Minecraft looks at the texture it is given for clouds, an then renders each pixel from the png inside the world (each pixel representing one "piece" of cloud.
It is perfectly understandable why this is like that, and it was most likely intended. However, to the regular player, it is considered a bug, as noone would expect clouds to be smaller inside (reverse tardis perhaps?).
It would be a nice addition to the game if connecting cloud pixels were rendered as one, but this is outside of the bug tracker's purpose.
My problem was not that only the half of the door got moved, because that's the intended command. Sorry if I wasn't clear, English is not my primary language.
What I meant to emphasize is that the upper part of the door snapped to the west side instead of staying where it was.
After some testing, I found out that it got fixed apparently. Now the top part just disappears as seen in the first 45 seconds (and how it usually works): http://youtu.be/YNvKPzqaU4U
I don't think this is a duplicate of said issue as the world was generated completely. I'll add the world save here.
Worldsave - Broken generation uploaded
Both - It's constant.
I did see that comment. I believe those holes would be loaded perfectly in the next few seconds. However, this world was loaded completely (I waied around a minute seconds while moving around), and there is water on the bottom, like it should be in an ocean biome.
Unless I'm being dumb, and not realizing that these are the same, I think this is a generation bug that happened in the internal server, and the other one is just how the server sends terrain to the client.
This still exists in 14w30c.
Can confirm that the dedicated server is having the issue too, and also that /gamerule doMobSpawning is causing it, however, gamemode didn't matter for me.
EDIT attachment
When hitting for the second time, the video doesn't show the button being pressed. That's because of it's framerate, it does get pressed like before, just quickly.
Video from 16w42a
Yes, I can confirm this is still an issue with 16w42a. I'll try updating the ticket in the future
The video I just uploaded didn't want to start when clicked, so I re-encoded it, it can be played now.
I can confirm this, also happens when the selector is @a, optionally with a valid scoreboard value (like @a[score_test=1]).
While @p could produce an error, @a should work even with just one player.
Interestingly, /tellraw @p and @a works fine for me.
This is still the case, as demonstrated in the video I just uploaded.
A workaround is to switch the triggered command block's type to impulse, and chain blocks react to them just as well, and it's only ran once.
