World generation cutted off by... Flying dirt?!!

I created a world to test the snapshot and suddenly chunk generation started to slow down. So I decided to go and see why world was not being generated. While testing a lot of things I placed a dirt block at the generation border and suddenly a line of flying dirt blocks appeared surrounding the generated chunks of the world.

In my opinion, the problem was getting the block placed instead of getting the error message "You can't place blocks outside the world"

Try attaching the world save. Does the issue still occur when relogging?

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?

Please force a crash by pressing F3 + C for 10 seconds while in-game and attach the crash report ([minecraft/crash-reports/crash-<DATE>-client.txt|http://hopper.minecraft.net/help/finding-minecraft-data-folder]) here.

Are you using Windows 10 (as in the Environment field) or Windows 8.1 (as in the Crash report) ?

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.

Hm, it should've done that automagically.

Download it from https://minecraft.net/download

Updated launcher, created a new crash report and uploaded new screenshot.

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.

A similar issue was fixed recently. Is this still an issue in 15w45a? If so, please explain the issue in detail and provide steps to reproduce it. Please also update the list of affected versions.

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.
