Updating project prefabs from 2018.2 to 2018.3

[TokyoWarfareProject]

actually, what is going on in above pictures is what is described here:

Prefabs created on 2018.2 loose data when dragged to hierarchy

After upgrading from 2018.2 if you open a prefab from the project window, all the scripts show the same data they had on before the upgrade, however if you drag the prefab into the hierarchy they are blanked, the same thing happens if you try to instantiate the prefab from a script.

I noticed it later, the 2018.3 messes up when dragged into the scene, I was comparing them using the scene prefab. I did “open” the prefaba and values seem right.
