Servers with modifications are not officially supported. Make sure that your key bindings are properly set and If you are having this issue too in singleplayer or in a vanilla server, update the issue to reflect it.
Reproduced in 1.14 Pre-Release 2, attached video testing it.
Turns out the "impossible case" is possible if you click on the base.
It seems so.
I just tested it in 18w21a with the following setup:
Placed a note block with a redstone clock that played it repeatedly
Spawned a bat near the note block
Went into spectator mode and spectated bat's point of view by clicking on it
The bat moving around didn't seem to change the stereo location of the note block and it moving away didn't seem to fade away the sound. Moving the cursor though, does change the stereo location of sound sources and the orientation of certain partices as if the player was rotating, though it doesn't because it's specating an entity.
Conclussion: Still reproduces in 18w21a
This is a security issue, the hotbar save and restore function as it currently is assumes that if a player is in creative it has certain level of trust in that server over normal players, which is not the case in creative servers where players being in creative mode is the standard. A malicious player could use this to create an item with malformed NBT tags, then login into a creative server, spawn that item and crash the server. Such a malformed item would otherwise be unobtainable without specific permissions (like /give), but it is now possible for any player in creative due to how the saved toolbars work.
Still an issue in 1.12.2.
Reproduced it while spectating a player in a multiplayer server.
The problem with randomness is that you never know for sure if it's truly random.
For example, I'm going to draw 6 random numbers between 0-9: 9, 9, 9, 9, 9, 9.
How do you know if there was a problem with randomness or it was just a very unlikely but possible streak?
@[Bot] Arisa Sorry for questioning your bot logic but i'm pretty sure this is the official minecraft version, just with a staging launcher :/
Unable to reproduce in 15w45a. New world generation is too fast to reach an area were chunks are still generating.
How it was reproduced in previous versions:
1. Find an area where generated chunks and non-generated chunks are together.
2. Place a block outside of the generated chunks
3. Wait for new chunks to generate
4. In the border of those new chunks you should see more blocks like the one you placed
That doesn't mean the bug it's fully solved, i could try to reproduce it in a resource-intensive preset that takes more to generate chunks.
Added 15w33c to affected versions, uploaded 2 new screenshots and new crash report for the version above mentioned. As you can see in the screenshots, this could be a potential exploit to farm diamonds or any other block.
Updated launcher, created a new crash report and uploaded new screenshot.
Actually, how do I update minecraft launcher? It doesn't seem to update itself when starting and there's no "Search for updates" button.
I'm using windows 10, i already noticed the game detects it as Windows 8.1 when launching game, in snooper settings and in crash reports.
When relogging the problem seems to solve. I was unable to reproduce the bug, but if I place a block outside the world, it still multiplicates infiniteley arround the world generation but It does not cut off chunk generation. Infinite block farm maybe? Should I mark this issue as private?
I was running the previus snapshot and Realms button doesn't appear, so when seing the button i found it strange
The server that I was atempting to enter was meepcraft.com could you try to reproduce it there?
I think this "bug" is rather useful, it has been used before in RPG-like adventure maps to move players into the next area upon resting. By contrast, if you want to prevent this from happening in your house in survival it should be as simple as properly covering your house's corners with blocks or moving the bed 1 block away from the corner. Or maybe you could instead use that in your favor and make a secret room or a hidden escape route... think about the possibilities!
