After update of Unity Editor all objects in scene lost references to any scene object.

I updated Unity because Unity told me there was new version to download and I clicked yes.
When the installation was done now suddenly ALL references are lost, but all objects are correctly in the scene. I don’t want to drag 100 objects into 100 inspector references when I update Unity. Is this normal to lose all reference?

I have not saved scene after this happent, I hope I can repair it? I’m afraid to trying to solve this alone.
Other questions in the forum are from 2014 or 2011, so they are too old.
Thank you.

I absolutely know that problem. Don’t be afraid to open the project again. It should all be right now.
The first time opening a scene after updating Unity this happens for some reason.

This is a very strange bug in Unity 5. I had exactly the same issue. Just open the project, and open the scene. Every reference should be correct now.

Let me know if it worked!

Just updated to 5.6.1 and lost some items, says missing prefabs in the Hierarchy. Tried opening the project again, same issue. Tried remvoing library and temp files, same problem. Not good when I have a few days to get this thing I have been working on for 2 years now ready for a presentation in Sydney on Thursday.

This happened to me when updating to 2017.1.2. But simply re-loading the project did not fix the problem. This was a big project (100s of hours work). We had some script errors (from deprecated support) that we fixed, but still have had no luck with the scene configuration. Is there an alternate solution?
