This one-chunk survival map includes multiple biomes (actual biomes, not just appearance), one-chunk Nether, and an End Portal. This was built on 1.19.2. This is a work in progress, specifically the Nether mob spawn issues.
Note:
-I am working on fine tuning the mob spawn issues in the Nether. You will want to break your portal once you cross over, and the same when you return to the Overworld.
-I have not made any changes to the End, yet.
-This map is a Beta, please let me know any suggestions/bugs you have.
