which mod prevents me from generating a flat world

If you're unable to generate a flat world in Minecraft, it could be due to several factors depending on the version of the game and any mods or plugins you might have installed. Here are a few possible reasons: 1. **World Type Settings**: Ensure that when creating a new world, you select "Superflat" as the world type. Sometimes, the option might be overlooked. 2. **Conflicting Mods**: Some mods might alter world generation, preventing you from accessing the flat world option. For example, mods that enhance or replace the terrain generation system (like Biomes O' Plenty or TerraForged) may interfere with world types. 3. **Server Plugins**: If you are trying to create a flat world on a multiplayer server, certain plugins may restrict world types for performance or gameplay reasons. 4. **Corrupted Installation**: In rare cases, your Minecraft installation may have corruption. You could try reinstalling Minecraft or the mods to see if that resolves the issue. To troubleshoot, you can: - Disable any recently added mods and test if the flat world option is available. - Check the configurations of your mods or server plugins to see if they restrict world types. - Try launching Minecraft without any mods to see if you can access the flat world feature. If you're still having issues, consider reaching out to forums or communities related to the specific mod or gaming platform you're using for more specific advice.
