Questions & Answers
1

Hi,
i have problem with prefabs. In new prefab editor my references to prefab’s childs objects are there. But when I drag’n’drop to scene (or create instance via script), the reference are gone and I got null ref exception. Do anyone have same issue?

“Reimport All” did the trick, works now

This happened to me as well, and “Reimport All” didn’t work. However:

My problem was with Odin plugin’s [ShowInInspector] attribute to a private field. After I changed [ShowInInspector] to [SerializeField] it worked fine.

This helped me a lot. Also, if you know which specific prefab is broken, you can do just a Reimport on that prefab to save some time.
