Hey, Unfortunately, a project sample will not replicate the issue, as the error is in the engine. I have seen this occur three times now and was able to replicate it. I tested this on two separate pcs on 4.17.2
Let me breakdown the steps to reproduce.
- Make a fresh c++ project
- Make a new c++ plugin using the Unreal plugin manager.
- Compile and reboot
- Inside project content, make a blueprint, sub-class from EditorTutorial
- Add some junk text and a tutorial stage just so it work (Probably not required)
- Move the tutorial blueprint to the plugin content folder.
That’s it, your engine is broken in all other projects. Try making a fresh new project and check your output log or try exporting a build, it will fail referencing the missing tutorial blueprint.
If you are able to replicate this, could you reach out to the engine dev team and ask if there’s a possible workaround fix, it’s kinda broken my whole engine.
