So I have a UEFN map that I want to duplicate. I tried the way to do a blank island and yhan migrate the level and it almost worked. The problem is that a big part of my map is using Referenced Content from fab and it didnt migrate. What is a problem?
Hi @georgik_n
Let me try to help you 
I share with you this short tutorial, check if you did each step by step.
If the same issue persists, go back to the original project and manually select all FABs that lost their references:
- Right-click > Migrate, or try copying them manually into your project folder.
I hope I have been able to help!
Have a nice day!
