Regeneration List

Later today, I will run a script that partially regenerated the world. It will check if a chunk contains man-made blocks, and if the chunk is absent of any unnatural materials, will regenerate the chunk.

If you do not want a chunk to be regenerated, it must contain one of the following blocks. These are the only blocks that cannot appear naturally under any circumstances and are available in 1.2.

Block of Diamond
Block of Gold
Block of Iron
