2b2t (map)

The 2b2t map was generated sometime in February 2011, and is hosted on the server 2b2t.org and formerly on 2b2t.net. The map is younger than the server itself which has been running since at most November 2010, as other maps have been used before the current map.

Before beta 1.3, there was a bug in world generation that made the x and z axis of certain blocks be flipped. The bug also changed bedrock, which means that bedrock in beta 1.2 and lower is different from beta 1.3. No chunks in 2b2t use the beta 1.2 pattern. The bug had actually been fixed earlier than 1.3, in a specific version of the server software craftbukkit from February 9, 2011.
