      World generation sometimes adds block ids wrongly into chunk section palettes, usually resulting in 16^3 blocks almost full of one block type or block types being exchanged within the chunk section. This happens very rarely and usually doesn't happen again (in the same place) when regenerating the world. Note that, for the few users affected, this happens relatively frequently.

      From the original description:

      Weirdly I actually broke a whole row of the blocks. on the top of the wood block on the edge and that was even the still image for the world but when I loaded it back in the blocks were there like I had done nothing.

      Blocks you break around the giant blocks of blocks stay the same,

      If I just punch the blocks to break them I cannot enter the space where the block disappears from. In general I cant seem to break the blocks myself because if i leave the area and the chunk loads back in (or save and quit then return), the blocks are still there. Only by natural decay methods does it seem to get rid of them.
