On Unreal Engine 4.26.2, I am trying to package a Blueprint/C++ mixture project for Win64.
However, I have encountered the following error:
LogMainFrame: Project does not require temp target
LogLauncherProfile: Found promoted target with matching version at ../../../Engine/Binaries/Win64/UE4Game-Win64-Shipping.target

Is there a conventional reason "Game target not found" is hit?
Although not clear why it worked, copying the default projectname.Target.cs file in the Source directory and renaming it projectnameGame.Target.cs (and also change the internal class name of that file to match) seemed to do the trick. There are now 3 Target.cs files in the Source directory.
At that point everything worked again... this seems weird but it works!
