Random chunk generation on crash

Resolved

I recently had a random chunk generate on a game crash. I was throwing eggs into my chicken farm and Minecraft crashed on me, when I rebooted the game my chicken farm had a chunk randomly appear in the side of it. The chunk also removed a portion of the villager farm I had been building.

Besides having a new chunk appear in the area, it moved the section of the villager farm (that the chunk replaced) to a new area. The doors and the entrance into the farm were all still intact, just moved about 100 blocks away. It also moved a random chunk of roofed forest into the plains beside it.

I just thought that this was a interesting glitch y'all should know about.

Please attach the crash report from ([minecraft/crash-reports/crash-<DATE>-client.txt|http://hopper.minecraft.net/help/finding-minecraft-data-folder]).

I am pretty sure the crash report you need is 2016-03-14-3

I say that because 14-4 shows that I took some of the screenshots I attached earlier.

There wasn't a crash, jist lag:

I'm sorry, but what exactly does that mean? Why did it generate 2 new chunks like that and move the section of the wall away? I have had a lot of strange things happen in this game but nothing like that. Lol, I don't really speak java script......

Something has damaged the chunk files. Either the game itself or something from outside (bad hard disk, bad SSD, etc..), but what that was cannout be found out from the log files or the world files.

BTW: That's Java, not JavaScript. Both share only the name but nothing else...
