While doing a fly over on my server of unexplored land, 1000's of blocks away from spawn, I noticed biomes started generating in around 10x100 strips that look TERRIBLE. I am wondering if this is a problem in all maps or just possibly weird seed?
here is a screen cap of plain, and swamp 'strips'. to the right there was jungle and plain 'stips'.
I've seen it happen too, though I believe it was the previous snapshot that I noticed it. I had these small desert strips of maybe 10 tiles wide ripping through things like mountains and stuff like bizarre stripes. On the plus side I found an abandoned mineshaft easy (was like viewing a chunk error).
