This mod is no longer needed with BetterEnd Forge 20.0.6+ and thus, has been abandoned!
The Problem
If you use BetterEnd (Forge) alongside LionFish API, you will notice that if you use the custom terrain generator (enabled by default if you use this mod), the custom terrain does not generate and the biome source gets completely messed up.
NOTE: This problem ONLY exist if you use the custom terrain generator which adds height variation to the end islands. It does not appear to exist with vanilla minecraft terrain.
BetterEnd Fix is NOT needed for 1.21+ as Lionfish API no longer have the intrusive biome config system.
The Fix
This mod simply blocks LionfishAPI's biome system only for the End dimension since I have not encountered any problems for other dimensions. From my testing, this has not caused any problems but if you end up with missing biomes that depend on LionFish API's biome slice features, you should make sure to add it's biomes to BCLib (Forge) biome configs to let BetterEnd handle the generation.
