Prevent Game Freeze During Large WorldEdit Selections

Why Freezing Happens

WorldEdit processes large selections and operations on the main server thread. Without this mod, complex operations can lock up your game client or server while calculations complete.

Using the Mod

1. Make your WorldEdit selections as you normally would with //wand and click points

2. Execute operations like //set, //replace, or //move without hesitation

3. The mod runs server-side, so your client won't freeze during processing

Best Practices

  • The mod is most effective when installed on the server, not the client
  • It doesn't speed up operations, but prevents the game from becoming unresponsive
  • If you're still experiencing lag, consider breaking large operations into smaller chunks
  • Monitor your server's tick rate — the mod prevents hangs but doesn't reduce CPU load

Your game will remain playable while WorldEdit works in the background.
