I backed up my project with Github, and in doing so I moved the project folder down one level, giving it a new parent folder. In doing so, I completely prevented Unreal Engine from detecting my project, meaning I need to edit the config every time I want it to appear in my launcher.
While I understand that all I need to do is move the folder back to its previous location, is there seriously no way to re-target where the launcher looks for the project folders, or to just add new targets? That seems like such a simple thing to do, and the only resources on the topic I’ve found date back to 2015, and none of them are permanent fixes.
