It used to be that when you got a new dweller (births, lunchboxes, or radio room), and moved them to the "right" room for them, it would count toward the objective. Now it doesn't (although I don't own a radio room this time, I've tested births and lunchboxes). I only get credit when I move a dweller I already had when I got the objective. As it wants me to assign 30 dwellers to the right room, and I didn't have 30 dwellers in the wrong room or in the wasteland when I got it, is it impossible now? Or is there a trick to make it work?
