我创建的ABM实际上是AnyLogic 8.4.0中的一种复杂的SIR（流行病学模型）。一切基本上都可以初始化，但是在初始化状态（在主状态）结束时会出现此错误：
Error during model startup:
root.user[0]:
root.user[0].agentStatechart: trying to start statechart twice
That is followed by a traceback that doesn't really seem too informative.
root.user[0]:
root.user[0].statechart: trying to start statechart twice
java.lang.RuntimeException: root.user[1]:
root.user[1].statechart: trying to start statechart twice

我尝试重建状态图，重命名状态图，重新启动anylogic，以及几乎所有常用的修复程序，以解决它们的错误，但这仍然存在。 我发现，如果我在总体中创建一个代理（然后动态创建所有其他代理），该错误将变为尝试两次启动第一个动态创建的代理的状态图。
