No mods, empty project with one prefab override used to make it viewable / editable.

There is a simple mistake, broken inheritance of a component, that is still present in 1.7. Please refer to detailed ticket here: https://feedback.bistudio.com/T197409
It would be easy to fix and prevent possible performance issues / bugs. Side effects unknown. Possible hit reg. problems. SCR_CharacterDamageManagerComponent on any prefab shows an unusual inheritance problem where the depth from the original component (or really the component template) is clearly wrong or stuck at a count of 1.
