ChunkCache question

[sphinxc0re]

That's a quickwin. I can't see though, what I am doing wrong with the chunk. I'm getting a 15x15 Chunk.
Here is my code

Code:

ChunkDesc:ReadBlockArea(ChunkBlockArea, 0, 14, 0, (ChunkDesc:GetMaxHeight()), 0, 14)

and this gives me errors and leads to the same result:

Code:

ChunkDesc:ReadBlockArea(ChunkBlockArea, 0, 15, 0, (ChunkDesc:GetMaxHeight()), 0, 15)
