修复 Create Simulated 绳索连接器崩溃

Fix for Create Simulated Rope Connector Crash

问题 / The Problem

在服务器中游玩时，当准星对准物理化结构上连接了绳索的绳索连接器（Rope Connector）时，游戏会立即崩溃。

When playing on a multiplayer server, the game crashes immediately when the player's crosshair is aimed at a Rope Connector that is part of a physicalized structure and has ropes connected to it.

原因 / The Cause

Create: Aeronautics 1.3.0 的 RopeStrandHolderBehavior.addServerStrand() 方法在客户端也会执行，但内部调用了服务端专属的 ServerLevelRopeManager，导致空指针异常。

The RopeStrandHolderBehavior.addServerStrand() method in Create: Aeronautics 1.3.0 is executed on the client side as well, but it internally calls the server-exclusive ServerLevelRopeManager, resulting in a NullPointerException (NPE).

修复 / The Fix

通过 Mixin 在方法开头添加客户端检查，阻止在客户端执行服务端逻辑。

This mod uses a Mixin to inject a client-side check at the beginning of the method, preventing the execution of server-side logic on the client.

兼容性

• Minecraft: 1.21.1
• NeoForge: 21.1.236+
• Create Simulated: 1.3.0

说明 / Note

这是一个临时修复补丁。一旦 Create Simulated 官方发布修复版本，本模组将不再需要。

This is a temporary hotfix patch. Once the official Create Simulated mod releases an update containing this fix, this mod will no longer be needed.
