1. Download the latest waterfall and pupur core
   2. Then start the server. Remember to create two sub-servers so that you can jump back and forth easily.
   3. Prepare the 1.20.4 client. Enter a sub-server and enter a paragraph at will.
   4. Then jump to another sub-server and the problem will recur.
