Random Optimization

Improved structure locate performance

Structure placements are now cached during locate checks, avoiding repeated registry lookups and placement-list construction. The cache is automatically invalidated whenever the active chunk generator state changes.

Safer resource-pack lookups

The ZIP resource index is now initialized with proper synchronization and safely published as an immutable map. Closing a resource pack now releases the cached index without mutating data that may still be accessed by another thread.

Reliable lazy_dfu configuration

The lazy_dfu option is now read during early Mixin bootstrap, ensuring that the DFU optimization is enabled or disabled before the affected Mixin is applied.

The existing compatibility behavior for Quick Pack is also preserved: resource-pack lookup optimization is automatically disabled when Quick Pack is detected.

Updated boat fall behavior

Backported modern boat fall-distance handling, including correct vertical-motion tracking, fall-distance accumulation, and reset behavior when landing.

Maintenance

• Removed an unnecessary Forge event-bus registration.
