Description

🐛 Describe the bug
This mod causes the server to crash. The issue occurs after integrating this mod into the All the Mods 10 (ATM10) modpack. At first, the server runs normally. However, as players explore the world, chunks stop loading, which appears to be a thread hang or deadlock. Eventually, the server crashes.
📋 Steps to reproduce
Add the async mod to the All the Mods 10 (ATM10) modpack on a server.
Start the server and let players join and explore.
Observe chunks failing to load over time, followed by a server freeze and crash.
✅ Expected behavior
The mod should not prevent chunks from loading or cause the server to crash.
❌ Actual behavior
The server crashes.
🖥️ Environment
🔧 Async version: 0.2.0+alpha-1.21.1
🎮 Minecraft environment (Client or Server): Server
🎮 Minecraft version: 1.21.1
⚙️ Modloader & version: NeoForge 21.1.233
📦 Other mods installed: All the Mods 10 (ATM10) modpack. (The crashes are suspected to be triggered by the Ice and Fire and Productive Bees mods).
