      If you write certain NBT to a sign, you can stop / pause all updates in the entire world you place the sign in, no matter how far away you are from other players. You can also resume or cancel the updates at will.

      This bug only works with spigot from my testing. I tested with: Vanilla (integrated & external server) PaperMC, Scissors

       

      Here is a video of the bug in action:
