Similar to MC-114174 which was dropped. This is apparently Not repeatable and it has happened at apparently random intervals and Minecraft versions to me.
A big blocky column of stone appears one "morning" and won't go away as seen in the screenshot.

Are there any error or warning messages in the log, for example about chunk errors?
