On project settings, you can edit Savior settings.
Set the supported base classes that can be respawned from scope.
There’s a filter there for both Actor classes and Components that can be respawned…
And on Slot class, you can define a filter of classes that can be saved to that Slot.
Both filters are set to AActor and UActorComponent base classes, by default.
You can pick only the base classes that matters to your design.
Anyway, I will check the code and see if mistakes there are made.
