有些MOD吧，你点选打开会提示如下：
A Mod caused an error [System.Exception]
Details:

既然报错了那就点关闭吧，结果还是提示如下：
A Mod caused an error [System.Exception]
Details:
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.ArgumentNullException: Argument cannot be null.

这完全看不懂了……

尤其是Harmony我已经删掉了这个模组了，怎么还在提示啊？所以，这个到底怎么解决？

订阅一个Compatibility Report，开一次游戏，他会生成一个报告告诉你哪些mod有冲突

Argument is out of range.
Parameter name: index [System.ArgumentOutOfRangeException]
Details:
No details
还有这种只报有问题，但是啥问题什么都不知道的提示……

进主页就进compatibility report的选项看报告，可以解决大部分兼容性问题

兄弟我一模一样的问题，求解
