C0.0.15a Missing Chunk

About
In c0.0.15a, ejmi and KizGalaxy dug out a chunk to bedrock. A chunk refers to a 16x16a area that extends from the bottom of the world to world height as that is how Minecraft generates and stores its terrain. The missing chunk is located in the corner of the c0.0.15a map that borders the c0.0.14a_08 map and the infinite ocean as of classic. The missing chunk is also the first breach into the Backrooms.
