Game crashes when loading new chunks (Exception generating new chunk, caused by ArrayIndexOutOfBoundsException: Index 268435455 out of bounds for length 32)

      I deleted some chunks from my world just as I did with pre-release 4 to reset them and save space. When I get close to where these chunks were, the game crashes no when it didn't before.

      What I expected to happen was...:
      The chunks should just load like they did in pre release 4. I commonly trim old chunks from my world using mca editor. this has always worked and I have never run into any issues besides the occasional ugly chunk border. With the new biome blending I'm fixing those spots in my world so that I no longer have the ugly borders.

      What actually happened was...:
      The game crashed.
