"Assertion failed on expression: 'pred(*previous, *i)' " is thrown on additively adding a new scene to a baked scene
Assertion failed on expression: 'pred(*previous, *i)' is thrown when a new scene is added additively to an existing baked scene having the "Auto-generate" checkbox off in Lighting settings. Refer the attached video
Steps to reproduce:
1) Download the attached project and open `s1Blue` scene
2) Check "Auto-generate" checkbox ON in Lighting settings and let the scene's lighting auto-bake
3) Uncheck the "Auto-Generate" checkbox in the Lighting window
4) Drag the 's1Red' scene from the Project folder to the Hierarchy to additively load it
Actual result: Assertion failed on expression: 'pred(*previous, *i)' is thrown when a scene is added additively to an existing baked scene
Expected result: No errors are thrown when a scene is added additively
