Describe the bug
Hallo,

I'm building a modpack for 1.20.1 and have installed a mod called Biolith to edit biome generation (replacing biomes from one mod with biomes from another mod to eradicate duplicates). I've always dealt with duplicate biomes from various world generation mods by disabling individual biomes, but this leads to world generation being inconsistent since the biomes are not replaced properly by the mods with good alternatives that blend well.

I found after some testing that this mod is what prevented the game from launching when C2ME was installed. There was no crash report generated since the error occurred before launch was even completed -- I've attached my latest.log. Let me know if there's anything else I can give you to help diagnose this issue.

To Reproduce
Steps to reproduce the behavior:

1. Install Biolith and C2ME.
2. Game crashes before it launches and does not generate a crash report.

Runtime info (please complete the following information):

• OS: Windows 10
• Minecraft version: Fabric 1.20.1
• Mod version: 0.2.0+alpha.11.16
• Biolith version: 1.0.1-alpha.1
• Fabric API version: 0.92.6
• Fabric loader version: 0.16.14

Checklist

• I am using the official version of the mod.
• I tried the latest development version but the issue persists.
• I searched for similar open issues and could not find an existing bug report on this.

Try disabling useEndBiomeCache as a workaround.

Disabling useEndBiomeCache solved the issue and the game is now able to launch -- I assume this has some kind of effect on worldgen in the End?
