Autoload Subscene not working?

I’m not sure if this is a bug or I’m just confused.

If I close a subscene for editing, it doesn’t seem to get loaded when I press the play button whether I have the “Autoload Subscene” checked or not.

So the only way my scene works when I load it is if all the subscenes are open for editing when I press play.

There is a check box for auto load, click on sub scene in the hierarchy, in the inspector

Yeah, it’s checked… and they aren’t auto loading when I press play.

Mmm , I’m not sure.
