I am trying to reduce memory usage on my Map, so I tried building HLOD on the level. After it was completed, I tried launching a session, and I got this error.
I don’t know what it is talking “copied content” I couldn’t even grab the output log because when the error appears, UEFN will freeze, and I can no longer interact with the engine, my CPU usage also shoots up to 100%, and I have to close UEFN with task manager.
Thank you for your report! We would like to look into this further, would you be able to submit a bug report using the form available here? Fortnite Creative
