Cross-Scene object references are not really supported by Unity and I even wonder how it worked for you in the first place :), but using Asset Blackboard parents can certainly help in many situations as long as you need variable that do no have scene object references. The thing that people mentioned in discord for self destructing managers is related to Singletons. A useful pattern which if you search for it, you will see how it can be implemented. Just search for “Unity Singleton” 🙂
