Regression
No
Prefab instances lose reference when a library is deleted and scripts used for reference are imported after project is loaded
To reproduce:
1. Extract attached project ("case_1185524.zip")
2. Delete Library folder and move Scripts folder out of Assets
3. Open project > "SampleScene" scene from Assets
4. Move Scripts folder back to Assets
5. In Hierarchy select "root-prefab" Game Object
6. Observe the "Inner" element in the Inspector window
Expected result: "Inner" element holds a reference to "inner-ref" Prefab
Actual result: "Inner" element doesn't hold a reference to "inner-ref" Prefab
Reproducible in: 2017.4.32f1, 2018.4.10f1, 2019.2.7f2, 2019.3.0b5, 2020.1.0a6
Note: The Prefab itself still holds a reference and reimporting it will fix the issue
