🚑 Legião v1.6.0 Hotfix is Live!
This is a critical update addressing the IndexOutOfBoundsException crash that occurred during world generation in version 1.5.0.
🛠️ The Fix
We identified a thread-safety conflict between C2ME (Concurrent Chunk Management Engine) and Feature Recycler.
- C2ME attempts to read/write biome features using multiple threads for maximum performance.
- Feature Recycler attempts to modify these lists in real-time to prevent potential loops.
- Result: This race condition caused the game to crash when generating biomes from the [Let's Do] suite.
Solution:
We have removed Feature Recycler. Extensive testing confirms that removing this mod resolves the conflict, allowing C2ME to handle world generation correctly and efficiently without crashes.
➖ Removed
- Feature Recycler (Caused
java.lang.IndexOutOfBoundsExceptionwith C2ME). - Lake Features Fix (Another crash problem)
✅ Status
- World Generation: FIXED. You can now create new worlds safely.
- Performance: C2ME remains active! You will still enjoy multi-threaded chunk generation and fast loading times for Distant Horizons.
- Biomes: All [Let's Do] biomes (Meadow, BloomingNature, etc.) are generating correctly.
⚠️ Recommendation: Update immediately if you were unable to create a world in v1.5.0.
