Disable Custom Worlds Advice Mod (1.21.11) – No More Annoying Message

Every Minecraft modder and custom world creator knows the frustration: that persistent "Experimental Features" warning screen popping up every single time you create or load a world with custom dimensions. Disable Custom Worlds Advice Mod eliminates that nagging advice screen entirely, letting you jump straight into your custom worlds without the extra click. With over 5.9 million downloads on Modrinth, it's clear the community agrees — this small quality-of-life fix was long overdue.

Key Features

• Removes the "Experimental Features" advice screen — No more clicking through the warning every time you load or create a world with custom dimensions or world settings
• Ideal for mod developers — If you're building a mod with custom worldgen, you can bundle this as a Jar-in-jar dependency to skip the advice screen automatically for your users
• Lightweight and focused — Does one thing and does it well, with no unnecessary extras or configuration needed
• Fabric and Quilt support — Works with both Fabric and Quilt mod loaders across multiple Minecraft versions

FAQ

Does Disable Custom Worlds Advice Mod work with Forge?

No, this mod is only available for Fabric and Quilt mod loaders. There is currently no Forge or NeoForge version available.

Is it safe to remove the experimental features warning?

Yes — the mod only skips the advice screen itself. It does not change how custom worlds or experimental features actually work in your game. Your worlds will load and function exactly the same way.

Which version of DCWA should I use for older Minecraft versions?

If you're playing on Minecraft 1.20.4 or earlier, use DCWA v5.0 or an earlier release. Version 6.0 introduced breaking changes and only supports Minecraft 1.20.5 and above.
