A fork of CliffBranch fixing a bug where the dark forest would generate without dark oak trees or crashed the game completely.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

This is a fork of CliffBranch that fixes a bug where the dark forest would generate without dark oak trees or would cause the game to crash upon loading dark forest chunks. I hope this issue gets fixed by Walls but for now there's this fork.

All it does is just remove a configured_feature file named dark_forest_vegetation.json, which fixes the issue (and probably sways a bit away from the mods vision but who cares if it works). As the original's license requires it's also licensed under Creative Commons 4.0, enjoy!

All credit ofc goes to Walls the creator of CliffBranch here's the link to his project:
