On the duplicated world do the following:

• Lower your Render Distance

• Raise your default Simulation distance to at least 4 (if you’re not on a realm)

• Lower your graphic settings

• Take your trinkets out of your bag, then run the following command (you will need cheats enabled):

  /event entity @e[type=hfrlc:trinket_menu] despawn
  

  Wait 30 seconds or less, then Logout then log back in.

• Go back to your trinket bag and re-equip your trinkets

If you're still experiencing lag, try reducing the number of active entities in your world—especially mobs that may be idling or duplicating in hidden areas. Excess entities can strain performance, particularly on lower-end devices. If that doesn’t resolve the issue, the lag may be device-specific.

Additionally, it can help to clean up your world list. Deleting unused or abandoned worlds frees up storage and memory, which can improve overall stability and load times. Some devices also benefit from restarting the game or clearing cache between long sessions. Keeping your game lean and your worlds tidy goes a long way toward smoother performance.
