Steps to Reproduce

Has not been reproduced internally - Licensee mentioned following these steps and receiving the error

  1. Create a project
  2. Add the GetModulesToPrecompile() function to the game and editor's .target.cs file, and list all the modules to be precompiled
  3. Open a command prompt and change into the Engine/Build/BatchFiles directory
  4. Run: "Build.bat <Editor target name> Win64 Development -precompile"
  5. Run: "Build.bat <Game target name> Win64 Development -precompile"
  6. Change to the root directory and run GenerateProjectFiles.bat with the -useprecompiled option
  7. Open the project and try doing a full rebuild of the game. It should be able to do so without compiling the engine bits you have precompiled.
