I have a problem with the editor. Every time I open it, the editor doesn’t show the C++ classes or even the C++ Classes folder. For them to appear, I need to create a new C++ class or recompile. However, all the Blueprints I’ve already created become invalid because they lose their parent class.
Random idea: you may be building your project in DebugGame Editor, while by default *.project launches the Development Editor binaries. And since they were never built - engine can’t see your classes.
