Why are Blueprint components not refreshed after code change?

Sorry for the long wait, I had a lot of work which unfortunatly does not involve UE.

It seems I do not succeed in compiling the master branch. Here is what I get :

  • 2> -------- End Detailed Actions Stats ----------------------------------------------------------
  • 2>ERROR : UBT error : Failed to produce item: D:\Mes documents\GitHub\UnrealEngine\Engine\Binaries\Win64\UnrealHeaderTool-Core.dll

PS: I can’t seem to find how to do simple ‘\n’ here.
