I followed the official documentation for version 5.6 to set up my project. In an initialized Blueprint project, I created a new C++ class, then right-clicked that class to generate a Blueprint. However, I couldn’t select this generated Blueprint in the GameMode dropdown. Additionally, after restarting the engine, it reported that the parent class for this Blueprint was missing.
Interestingly, this issue doesn’t occur if I initialize a C++ project instead. Similarly, when I used version 5.5.4 of the engine to initialize a Blueprint project and followed the same steps, the problem didn’t happen. What could be causing this specific issue?
