V3.2.3 Overview

This patch fixes a rare but nasty stall caused by a blocking multichunk integration path. Integration is now fully asynchronous and completion‑hooked, so heavy worlds no longer freeze when a multichunk finishes computing.

Async Integration Fix

• Removed blocking join() calls in multichunk integration
• Integration is now completed via completion hooks only
• All integrates are scheduled safely on the server thread
• Prevents async worker stalls and eliminates rare deadlocks under load

Stability Impact

• Fixes long‑session stalls seen in heavy modpacks
• Improves worldgen consistency during high‑pressure chunk work
• Reduces sudden server “hangs” caused by multichunk sync waits
