What is happening and how can I fix it?发生了什么，我该如何解决？ Thank you.谢谢你。
OBS: Stackoverflow won't let me post my question because it's mostly code, but I don't know what else to add that will contribute to the understanding of the question... OBS：Stackoverflow 不会让我发布我的问题，因为它主要是代码，但我不知道还有什么要添加的内容有助于理解问题......
