Chunk error

From FroobWorld Wiki
A couple of chunk errors near the town of Norway on map 8. One of the chunk errors has part of someone's building.

Chunk errors are chunks that have been incorrectly moved by the server to a new location. They occur as a result of world corruption which will most commonly happen after a server crash.

Chunk errors can completely deface parts of the world and destroy unlucky players' buildings. The last map to contain any chunk errors was map 8.
