What's new

EngineCore v1.0.1 Hotfix 2 is now officially available for Minecraft NeoForge 1.21.1!

What's Changed & Fixed:

  • Fixed Mob Spawning Crash: Resolved InvalidMixinException in MixinGoalSelector caused by an outdated @Shadow reference during mob entity creation.
  • Fixed World Generation Freeze: Resolved a server-thread deadlock where neighbor updates queried unloaded chunks during spawn area generation (freezing at ~16%).
  • Production RefMap Added: Generated and bundled the missing enginecore.refmap.json into the production build to fix mapping lookup errors across heavily modded environments.
  • Full Modpack Stability: Restored full compatibility with performance packs (Sodium, Lithium, C2ME, ModernFix, ImmediatelyFast, Ksyxis).

Compatibility:

  • Minecraft: 1.21.1
  • NeoForge: 21.1.65+ (tested up to 21.1.250)
  • Environment: Client & Server (Server-only supported)
