Chunks specific to a row render, then de-render randomly.

Is this still an issue in 14w30c ?
If so, please attach a new crash report.

Something slightly different happened this time. I had to force a crash and it started instantly instead of when I restarted.
It still happened because I set my render distance to 10 chunks.
