Hey!
Thanks a lot for great job! Engine is awesome 
I have some issues with compilation win32 projects (DebugGame, Development or Shipping) on Visual Studio 2017.
This is Output from compiler:
1>------ Build started: Project: MedievalTales, Configuration: Development_Game Win32 ------

Here the same issue for ue4.15:
Will this be fixed in future releases?
