I'm trying to place a Banner of Potema (PotemaBanner02) in a custom home. I can add it to the render window and use the rotation widget to orient it, but I can't move it from its starting location. When I try to select it with the mouse, I get the object behind or beneath it as though it weren't there. I've also tried selecting it from the cell window, which works, but it deselects as soon as I try to move it.

Any ideas?
