Unreal Engine Issues and Bug Tracker (UE-6096)

Description

Adding a new code class derived from AnimInstance will cause the Visual Studio build to fail in a project based on the code Vehicle template. The build errors indicate that there are problems in the ShowFlags.h file:

WORKAROUND:
Add the line #include "EngineBaseTypes.h" to the ShowFlags.h file.

Steps to Reproduce

Create a new project using the code Vehicle template.
Build the project in Visual Studio.
Open the project in the Editor.
Add a new code class to the project derived from AnimInstance.
Close the Editor.
Build the project in Visual Studio.

RESULTS:
The build fails.

EXPECTED:
The build succeeds.
