🏆 Key Improvements
🆕 Added Mods (7)
- AllTheLeaks (Memory Leak Fix): Fixes memory leaks in Minecraft and related components, preventing memory from draining during long play sessions.
- Jade Grass Fix: Jade now correctly detects entities hidden in tall grass — instead of just "Grass", you see the actual mob's info.
- Just Enough Freezes (JEF): A genuine client-side optimization mod that improves performance and reduces loading times for Just Enough Items (JEI) in large modpacks.
- Bye?Pregen!: A server-side world generation performance mod for 1.20.1. Reduces MSPT spikes and server freezes — ~50% lower exploration lag, 30–70% lower generation-related MSPT, up to +95.2% chunk-generation throughput. Fully compatible with C2ME & FastNoise. Not compatible with Noisium & AntiXRay (neither is in the pack, so you're good to go!).
- Nyf's Spiders: A spider enhancement mod that improves spider behaviour and integrates seamlessly with Spider Overhaul.
- Spider Overhaul: A mod that improves Minecraft's spiders! Adds many redesigned variants (wood, ice, moss, glowing crystal, red mushroom and more), with new spiders, armor trims and a spider boss planned.
- Weaker Spiderwebs: Makes cobwebs far less of a nuisance — no more getting trapped or slowed to a crawl.
