Hi ,
I ran some experiments in 4.9 as well as our latest internal version of the Engine and was able to see the results that you described. I am in the process of trying to gather more information regarding whether this is being triggered by something on our end, or if it is internal to Visual Studio. Unfortunately the end of year holidays may hamper my ability to get in touch with some of the developers who would have more insight into this.
If you find yourself needing to rebuild your project, we have recommended the following process in the past:
- Delete the Binaries, Build, and Intermediate folders for the project.
- Delete the project .sln and .suo files.
- Right-click on the project’s .uproject file.
- Select Generate Visual Studio Project Files.
- Open the newly-created .sln file in Visual Studio.
- Build (not rebuild) the project in Visual Studio.
