Feature Recycler
A simple mod that prevents crashes between world generation mods caused by Minecraft's Feature Cycler.
About this Mod
What does this mod do?
Fixes the "Feature order cycle" error when mods add placed features in different orders between their biomes. It does this by automatically recycling(resorting) their biome features to respect the rules set by a previous biome containing the same 2 elements.
It will now also silently log and tell you which features may have conflicted between which mods and how many crashes were prevented:
[01:55:31] [Worker-Main-11/INFO]: Starting feature recycler...
[01:55:32] [Worker-Main-11/WARN]: Moved placed feature "minecraft:flower_default" from index 2 to index 4 for biome "biomeswevegone:sakura_grove". Placed Feature index rules set by biome "wythers:sakura_forest".
[01:55:32] [Worker-Main-11/WARN]: Moved placed feature "minecraft:flower_cherry" from index 4 to index 2 for biome "biomeswevegone:sakura_grove". Placed Feature index rules set by biome "wythers:sakura_forest".
[01:55:32] [Worker-Main-11/WARN]: Just prevented a crash between biomeswevegone and wythers! Please report the issues to their respective issue trackers.

What is the Feature Order Cycle error?
The error looks similar to this:
java.lang.IllegalStateException: Feature order cycle found, involved sources: [Reference{ResourceKey[minecraft:worldgen/biome / wythers:sakura_forest]=net.minecraft.class_1959@3fddd9c5}, Reference{ResourceKey[minecraft:worldgen/biome / biomeswevegone:sakura_grove]=net.minecraft.class_1959@337bfcbf}]
or with Cyanide:
com.alcatrazescapee.cyanide.codec.FeatureCycleDetector$FeatureCycleException: A feature cycle was found.

Feature Recycler server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 4 GB RAM is allocated and the loader matches the mod version (1.21.1). You can switch loaders with one click in the panel.
Is Feature Recycler compatible with fabric and forge and neoforge and quilt?
Feature Recycler officially supports fabric, forge, neoforge, quilt for Minecraft 1.21.1, 1.20.1. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Feature Recycler – how to optimize performance?
Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if Feature Recycler consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
