Adding ProceduralMeshComponent Class to a project prevents the code from compiling

After adding a classed based on ProceduralMeshComponent the code for the project does not compile any longer.

**This is a Regression - Adding ProceduralMeshComponent class would compile successfully in 4.12.5**

Working:
4.12.5 Binary - CL 3039270

Broken:
4.13 Preview 1 Binary - CL 3072953

Edit:
AnswerHub member submitted a PR for this issue: https://github.com/EpicGames/UnrealEngine/pull/2678

1. Open UE4 Editor (any project)
2. Add code to project based on ProceduralMeshComponent (MyProcMeshComp)
   • Note editor error message when class is added
3. In Visual Studio, compile project

Result:
Compile process fails

Expected:
Compile succeeds
