1.  LogWindows: Error: Assertion failed: !bCleanedUpWorld \[File:D:/Build/++UE4/Sync/Engine/Source/Runtime/Engine/Private/World.cpp\] \[Line: 4092\]

场景流中的子场景重复包含

1.  ### If I edit any property of my character, editor crashes. But if I duplicate the BP, then it works? ###

Sometimes when editing any sort of blueprint class, you must delete it and then re-add it back into the editor or you get weird crash or bugged out blueprints. When you copied it, it created a new/fresh updated blueprint instance that was correct, while the original one was stale and bugged.

I"ve had it happen a couple times, but not for a while now. The only way I could fix it was by either redoing the affected BP or duplicating it, and redoing references etc.

复制一份，使用Replace Reference和重定向修复。如果遇到Replace Reference提示需要关闭StartUp时，把ProjectSetting里的Editor起始场景Clear掉。

1.  UPROPERTY崩溃，定位在check(TextStartIndex <= TextEndIndex); 解决方案：避免在代码中使用中文
2.  LogOutputDevice: Error: === Handled ensure: ===  
    LogOutputDevice: Error: Ensure condition failed: Component->HasBegunPlay() \[File:D:/Build/++UE4/Sync/Engine/Source/Runtime/Engine/Private/Actor.cpp\] \[Line: 3457\]  
    LogOutputDevice: Error: Failed to route BeginPlay 解决方案：继承自UE4基类的函数一定要调用Super::XXX()
3.      UE4编译报错:命令行 error D8049: 无法执行“C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.16.27023\bin\HostX64\x64\c1xx.dll”: 命令行太长，无法适应调试记录
        
        解决在XXX.build.cs文件中添加:bLegacyPublicIncludePaths = false;
