Hi MaroonBerats,
Feel free to re-phrase if I’m missing what you’re asking, but focusing in on the idea of an actor destroying all of its children then destroying itself. (Sounds morbid when taken out of context 
)
I just wired this up, and I think it shows the behaviour you’re after. (All children destroyed instantly, then 5 seconds later parent class destroyed, this code is in the parent class (A))
Hope that helps, welcome to The Forums!
