Terrain paint functionality is disabled in second Inspector when you close initial Inspector



How to reproduce:
1. Create a new project
2. Create a Terrain (right-click in the Hierarchy tab -> 3D object -> Terrain)
3. Add one more Inspector tab (right-click on any tab -> Add Tab -> Inspector)
4. Notice that one inspector window has the Terrain Inspector disabled under the message "Inspector tab is a duplicate. Paint functionality disabled"
5. Close the functional inspector

Expected result: Terrain paint functionality is working
Actual result: Terrain paint functionality is disabled

Reproducible: 2018.3.0b7, 2018.3.3f1, 2019.1.0a14, 2019.2.0a1
Not reproducible: 2017.4.18f1, 2018.3.0b6, 2019.1.0a7 (terrain is editable with both inspectors)

- Terrain paint functionality is disabled, even when deleting or creating a new terrain

  1. Resolution Note (fix version 2018.4.1f1):

    The terrain may be deselected in the Hierarchy and then re-select for the new Inspector to be active.

    Had this issue with one of my game backups in 2019.1.3f.1 finally resolved itself when I updated the entities package to preview 0.1.1

    I wouldn't call this fixed if it's still happening.

    Just upgraded from Unity 2018.2.20f1 to 2019.2.17f1 (64 bit) in hopes to use the new features. I see they fixed the latency that was caused by the new prefab system back in the 2018.3 series, which is why I've been waiting so long.

    However, all my terrains, even brand new blank terrains are un-editable. Stating the message "NOTE: Inspector tab is a duplicate. Paint functionality disabled."

    So no, this bug is definitely not fixed.

    I found this in a thread talking about the issue, this is the creator of vegetation studio's response.

    "Hi. I had a look at this. Unity added some internal test that did not validate the inspector as "itself" when extended with reflection.

    I will make a workaround and update. For now delete the ExtendedTerrainEditor.cs file and things should work."

    This is the thread:

    I had this issue also, but it is absolutly no problem, just update Vegetation studio and after that update the Unity Package, mostly the Jobsystem. (read the console)
    This is a normal Issue, Unity is highend software and has ridicolously cool features this brings the need of maintenance with it. solving this problem takes 2 minutes!
