Yah I wish they would clarify this. I don't envy the devs on this one though because on one hand if you cant remove someone with a room then you're stuck with the person, but on the other hand if you CAN kick someone with a room then someone could get kicked because their FC leader was in a bad mood and lose their investment. They haven't even clarified if it's going to be a permission the leader can set, though that could cause drama in and of itself if FC leaders get selective.
