      The bug

      The spawn chunks used to be 16x16 or 16x17 or 17x16 or 17x17 chunks.
      Since the recent snapshots the size changed to 23x23 chunks.

      • Visualisation of the spawn chunks on the top right:

      Note: Since 19w08a the spawn chunks are not actively loaded anymore.

      How to reproduce

      1. Download Spawn Chunks Test (1.13.2).zip and Spawn Chunks Test (1.14).zip
      2. Open the "Spawn Chunks Test" World in 1.13.2
      3. Activate and/or deactivate the levers of the clocks of the command blocks
      4. Lower your rendered distance to a minimum
      5. Move away from command blocks and observe the evolution of messages in the chat (If the messages still appear despite being away from a hundred blocks, it is that the chunk is still active. Otherwise, it is not active.)
      6. Repeat the experiment in 1.14+
