故障截图：

问题原因：

spigot entity 的初始化时， initializeEntityActivationState 存在 level 非空，但 spigot config 不存在的情况（如在 create 模组蓝图加载时） 猜测是机械动力 com.simibubi.create.content.schematics.SchematicChunkSource 在加载蓝图时创建的 DummyLevel 实例导致的。不同于 net.minecraft.server.level.ServerLevel 实例，后者在构造时会初始化 this.spigotConfig，而 DummyLevel 不会

修正方式：

在 config = null 时 initializeEntityActivationState 默认返回 false（构造模组自定义的Level实例及其中的entity时，让spigot不干预）避免因 NPE 导致蓝图加农炮失效

测试结果：

蓝图加农炮正常加载蓝图
