How to Load an Existing World That Uses Experimental Features Without the Warning

Why Loading Triggers the Warning Too

The experimental-settings popup does not only appear when you create a world. It also appears when you load a world that already has experimental features enabled — for example, a world you started with a datapack that uses experimental flags, or one created in a snapshot with features that later became experimental. Every time you open that world, Minecraft asks you to confirm you understand the risks.

Loading Straight Into the World

Yeetus Experimentus removes that confirmation step on load as well, so opening such a world goes straight to the loading screen.

1. From the main menu, choose Singleplayer.

2. Select the world in your list.

3. Click Play Selected World.

Instead of a warning screen, the world begins loading immediately. This is especially useful if you keep a long-term world that uses experimental features and you open it frequently — the repeated confirmation becomes pure friction.

Note that the mod only suppresses the popup. It does not change how experimental features behave, and it does not make an experimental world any safer. Back up worlds that rely on experimental features before major updates, since those features can still change or break between versions.
