Though it seems to not even work like that at all with the new studio UI, with it not selecting children for shift click:
Yeah, I was testing the new explorer and noticed this too.
One can call it a fix, but I’m not 100% sure.
I’ll go report it anyway and see what they have to say.
Im pretty sure that is because you are using shift click and that creates new array each time, so if you were to use ctrl it should’ve not heppened likely
