Feature Recycler

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.
