YapiFix

<span style="color:#e67e23">YapiFix — Universal Worldgen Crash Fix (Forge 1.20.1)</span> YapiFix is a lightweight **compatibility patch mod** for Minecraft 1.20.1 modpacks. It is designed to prevent _Feature order cycle found_ / FeatureSorter worldgen crashes caused by inconsistent placed-feature ordering between biome and worldgen mods. <span style="color:#e67e23">What changed in 2.0.0</span> Earlier versions of YapiFix fixed a small number of known mod conflicts manually. Starting with **YapiFix 2.0.0**, the mod uses a broader universal stabilization approach: it normalizes feature ordering after biome modifiers have finished running, helping prevent feature order cycles even when the exact conflicting mod pair is unknown. <span style="color:#e67e23">What YapiFix does</span> * Helps prevent FeatureSorter / feature order cycle crashes * Applies a deterministic feature order during world generation * Runs as a final compatibility pass after other biome modifiers * Keeps existing targeted fixes for known problematic cases * Works as an “install it and forget it” worldgen compatibility patch <span style="color:#e67e23">What YapiFix does not do</span> * Does not remove biome features * Does not remove biomes * Does not disable worldgen mods * Does not fix unrelated crashes caused by broken datapack JSON, missing registry entries, invalid configured features, or other mods’ mixins <span style="color:#e67e23">Useful for modpacks with</span> * Atmospheric * Biome Fest * Aromatic * Blueprint-based biome mods * Large modpacks with many biome/worldgen mods <span style="color:#e67e23">Works with</span> * Existing worlds * New worlds * Datapacks * Large modpacks <span style="color:#e67e23">Target Minecraft Version</span> * Forge **1.20.1** <span style="color:#e67e23">Notes</span> YapiFix was created to fix real-world worldgen crashes in production modpacks. Version 2.0.0 changes the philosophy of the mod: instead of only patching individual known conflicts, YapiFix now aims to prevent this entire class of feature-order crashes automatically. <span style="color:#e67e23">Usage &amp; Permissions</span> All rights reserved.
