world.setBlock negative position

[jdSteven01]

If I use negative number in setblock position, chunk error occurs!
please fix it.
(or my mistake?)

I could not replicate the bug. Are you running the newest version?

[jdSteven01]

hmm...
see this:
please see minecraft version.

code:
for(int a = -1023; a < 1024; a++){
for(int b = -1023; b < 1024; b++){
world.setBlock(a,10,b...
}
}

so, minecraft 1.8 below:
(red : error)

or my computer's error?

Found the cause of the error in NBTExplorer.
normal chunk:

error chunk:

so, I change your code.

Region.java, line 195

chunk = new Chunk(this, chunkX, chunkZ, layers);

->
chunk = new Chunk(this, chunkX + (xPos * 32), chunkZ + (zPos * 32), layers);
