Chunks appear to be "scrambled" for lack of a better term. I noticed the usual rectangle shaped landmass rotated 180 degrees, but these were individual and smaller groups of chunks that seemed to be in the wrong place altogether.

What is the name of the world, and if there is a name, has it been used before?

it was Kitt's world but I had deleted the one that was named that from the pre-releases beforehand. I messed with it some more and it seems to happen sporadically regardless of name.
