I tried to migrate some nice blueprints from Content Examples project by Epic. Content Examples run as project well, but after migration to my test project it crashing every time I start preview. I was sure, it happens because I placed some blueprints on map (like a door), but I see it crashing every time, even when they are not placed on map, just in project structure. I check some solutions, but nothing helps. On migration stage I had any problems, message was success. Any help appreciated!
